This is more of a major annoyance than anything that's stopping me from doing my work, but I somehow seem to have had Active Desktop on my work XP machine get corrupted and now can't get it back working again.

I've tried browsing to C:\Documents and Settings\%my-user-name%\Application Data\Microsoft\Internet Explorer and changing, deleting or replacing the Desktop.htt file, but it's not achieving anything.

The error I was previously getting when trying to click the "Restore my active desktop" button was:

Internet Explorer Script Error

An error has occurred in the script on this page.

Line: 65 Char: 1 Error: Object doesn't support this action Code: 0 URL: file://C:/Documents%20and%20Settings//Application %20Data/Microsoft/Internet%20Explorer/Desktop.htt

Any ideas?
