The first thing to try: run it in a new Windows account. If it works there, something (unknown) is wrong with your current account. Just copy all your files to the new account and continue using that.
If it doesn't work their either, it's a Word problem. Then uninstall and reinstall should work. There's no good reason why a new install wouldn't work in a new account.
Only delete the old account after some time, if you're sure you don't need it any more.
I am running Word 2003 under Win7. Until yesterday no problems for over two years. All of a sudden, I can not access the main toolbar within Word. When I click on "File" or any other option, the drop down expands briefly then disappears and when I hover over it I get a + (with arrows top and bottom).
I have uninstalled and reinstalled Word, repaired it and done all the usual troubleshooting problems recommended by Microsoft:
"This article shows you how to use the Troubleshoot utility to turn off the following components. These components
are typically loaded during Word startup:
The Word Data registry key
The Word Options registry key
The Normal.dot global template
Add-ins and templates
The Options registry key"
None of these cures the problem. I can run Word from the command prompt in the safe mode, but . . . .
I have scanned for viruses and found none with Trendnet.
Can anyone suggest something else??
