"Error on Page" when attempting to add an attachment in Web

When trying to add an attachment to an assignment or discussion message in WebCT Vista or CE 6, some users have reported seeing an "Error on Page" message in their browser.

There are a number of possible causes for this error; most can be resolved by following WebCT's Browser Tune-Up instructions.

* Ensure that the document you are trying to upload is not open in another program on your computer. For example, if you want to upload a Microsoft Word document, save and close the document first.

* If using the Internet Explorer browser, ensure that the "Display a notification about every script error" option is not checked:
1. In Internet Explorer, from the Tools menu, select Internet Options
2. Click the Advanced tab
3. Scroll down and uncheck Display a notification about every script error
4. Click OK to save your changes
