I cannot login to
Blackboard between 7:00 AM and 7:30 AM on weekday mornings.

When I add a file
using the File Exchange in the Group Pages area of Blackboard, a
message box appears on the screen. The message says, "This file
will be added but not sent. In order to send the file, please use the
Send File button. Send File can be used to simultaneously Add and Send
a file." There is not a Send File button. What do I do?
-
When I use the e-mail feature in
Blackboard to send e-mail to someone, the message is rejected by AOL.
My e-mail address as registered in Blackboard is also AOL.

My instructor uses a "Learning
Unit" in the Blackboard course. When I start the learning unit, I
cannot go through the units sequentially: my only option is to save it to my
computer one file at a time. I'm
using Windows XP and Internet Explorer 6.
-
When I click the
login button on Blackboard, I receive the message "
Base64Decode
error '800a0001' Bad Base64 string.
/bin/n_lib Base64.asp, line 45"
-
When
I click on a PowerPoint presentation linked within Blackboard, I get
only an blank slide in edit mode rather than the presentation. I'm
using Office XP.
-
A
"file not found" error message is displayed when using
Microsoft Internet Explorer to display a Microsoft Word or PowerPoint
document that has been converted for Web presentation. Netscape
Navigator displays the files okay.
I cannot
login to Blackboard between 7:00 AM and 7:30 AM on weekday mornings. When
I attempt access Blackboard, the login page does not appear.
(10/11/2006) This occurs because the
Blackboard system is taken offline at those times for routine maintenance.
If you experience this problem, wait until after 7:30 AM and then login.
If you wish to take a test or quiz, be sure to complete and submit it
before 7:00 AM.

(5/30/2002) Ignore the message. This
message is displayed when you Add a file in the Student Drop Box. It
should not appear when you Add a file in the File Exchange. Hopefully this
software bug will be fixed in a future release of Blackboard.

When I use the
e-mail feature in Blackboard to send e-mail to someone, the message is
rejected by AOL. My e-mail address as registered in Blackboard is also
AOL.
(2/13/2002) AOL's mail servers reject mail that has an AOL address in the "From:" line
that comes from a mail server other than AOL's. This means that mail from one AOL user to another sent from Blackboard will not work.
To the best of our knowledge, AOL appears to be the only major ISP that has this
restriction.
This has to do with AOL not allowing redirected mail.
This problem is caused by technology beyond
the control of KCC. It seems unlikely that AOL will change how their mail
servers handle mail. Blackboard is investigating how to solve the problem,
but the earliest a work-around is expected is their 2003 version of
Blackboard.
The only work-around we can suggest is to
use an e-mail address other than AOL. KCC can provide you with an
e-mail account.

My instructor uses
a "Learning Unit" in the Blackboard course. When I start the
learning unit, I cannot go through the units sequentially: my only option
is to save it to my computer one file at a time. I'm
using Windows XP and Internet Explorer 6.
(4/25/2002) This appears to be a problem
only on Windows XP and is the result of Microsoft changing how some
options are set in an effort to improve security. This is one way (I hope
there is an easier way, but I haven't found it) to get learning units to
work properly.
- Open Windows Explorer (that's right,
Windows Explorer, not Internet Explorer)
- Click "Tools" on the Menu Line
and then "Folder Options..."
- Select the "File Types" tab
and then scroll to the document type that you want to open
automatically. (You will have to complete this procedure for each file
type— ppt, doc, wps, wks— you want to open automatically and each
computer on which you want this to work.).
- Uncheck the "Confirm open after
download" option
- Check the "Browse in same
window" option.
- Click "Ok" then
"Close"

When I click
the login button on Blackboard, I receive the message "Base64Decode error
'800a0001' Bad Base64 string. /bin/n_lib Base64.asp, line 45"
(9/04/2002) This error message has nothing
to do with KCC's Blackboard. The message may also occur when the same
computer is used on other Web pages where a login is required. When the
login button is clicked, CommonName software redirects the browser to
www.commonname.com, which then
this error message. CommonName software can be automatically installed
without the user knowing about it as a result of simply clicking a link.
This error can be circumvented by simply
un-installing the CommonName program on the infected computer. Click on
"Programs", then "Settings" and finally "Control Panel" to find the
"Add/Remove Programs" icon. Double-click on this and then locate the
CommonName program in the list. Remove it and reboot your computer.

When
I click on a PowerPoint presentation linked within Blackboard, I get
only an blank slide in edit mode rather than the presentation. I'm using
Office XP.
(2/03/2003)
Office XP users must apply the most recent Office Service Pack to avoid
having PowerPoint trying to open files with a .ppt extension in edit mode (which it is not allowed to
do and thus produces a white screen only).

A
"file not found" error message is displayed when using
Microsoft Internet Explorer to display a Microsoft Word or PowerPoint
document that has been converted for Web presentation. Netscape Navigator
displays the files okay.
(2/03/2003)
Many "file-not-found" errors result from Microsoft Word or PowerPoint
documents that have been converted for Web use. In some cases, using
Netscape Navigator as the browser instead of Microsoft Internet Explorer
will allow you to access the problem.
To fix the
problem, notify your instructor (and give them a link to this write-up) or
KCC Tech Support. In the case of Word, the problem is due to Microsoft Office's use of
vector markup language (VML) to describe images, and Internet Explorer's non-standard
preference of the VML src attribute over the HTML src attribute. When the
instructor uploads a Web page to Blackboard, the uploading scripts automatically recognize the IMG tags and correct their src-attributes to
the actual location of the uploaded image file. However, they will NOT correct the VML src attributes, meaning that IE won't
find and display the images, whereas Netscape will. In the case of
PowerPoint Web page conversion, the default setting is to organize all files into a
folder with just a little redirector page outside same folder. When zipping
up these files, it is necessary to store path information, so the folder will properly be recreated when uploading to Blackboard and
unzipping the archive. In WinZIP 8.x this info is stored by default, but in
WinZIP 7.x one has to check the box to "save extra folder info" to avoid "file-not-found" errors.
