A number of issues in Blackboard have workarounds described below. You may also wish to check the section on browser-related issues if you don't see your problem here.
This problem occurs in recent Mac OS systems with recent browser upgrades. The scroll bar is supposed to appear when needed, but seems to not always appear.
It's possible that your student prepared the file on a Macintosh computer without the Office file extensions turned on (which produced a file name such as "essay" instead of "essay.doc"). You should be able to open the file if you change the file name to include the .doc file type extension (you may need to use .docx if the .doc doesn't work). It is also possible that your student is using Pages on the Mac; you can ask your student to save the file in a Word document format and re-submit it.
You can't seen the last student in your class, and if you re-order the Grade Center in reverse alphabetical order, you can't see the first student (who should now be at the bottom).
Fix no. 1: This problem may be happening if the text size is too large. Go to the View menu of your browser, find the Zoom or Text Size option, and make the text smaller. You may need to reload the Grade Center for this change to go into effect.
Fix no. 2: The problem could also be related to the scroll bar setting in Windows. This can be fixed by changing the Windows XP scroll bar size back to 20 or smaller.
Here is how to change the scroll bar setting in Windows XP:
For Windows 7:
You student attempts to submit an assignment and receives an error message with a long error id number and a message telling you to contact the System Administrator. This is probably caused by the name of the file containing some character other than letters, numbers, underscores or hyphens. Ask the student to rename the file with a shorter name with no special characters (no commas, extra periods, pound signs (#) or other non-letter, non-numeric characters). If this does not work, then empty the browser cache (Internet Explorer: Tools, Delete Browsing History, delete temporary internet files; or Firefox: Tools, Clear Private Data, make sure Cache is checked) and submit the file again.
You are attempting to submit a paper to be checked and receive an error message stating that you are not logged on. This seems to affect Macintosh users and the solution here is to "enable third-party cookies." How to do this depends on your system and which browser you use:
If you are using Firefox, then it's Preferences, click the Privacy tab, check Accept Cookies from Sites and keep until they expire.
If you are using Safari, then it's Preferences, click the Security tab, and check Accept Cookies -- Always.
And if you are using a Windows computer, it doesn't hurt to check the cookies as well:
Firefox: Tools -- Options, Privacy tab, check Accept third-party cookies, keep until they epire.
Internet Explorer: Tools -- Internet Options, Privacy tab, set the slider bar to Medium High.
