I am using Word 2003/SP3 with Windows 7.
Sometimes when I try to open a word document, I am prompted "The command cannot be performed because a dialog box is open"
I click OK, and underneath is a 2nd prompt saying "word automatically saved changes to the normal document template. do you want to change it? Yes/No

Also when I try to close a word file it takes ages, and then comes up with "not responding" - and eventually prompts - "The normal file already exists. Do you want to replace the existing file?"
Then usually comes up with - "Microsoft Office Word has stopped working - Windows is checking for a solution to the problem"

And so it goes on and on - most frustrating.
I have looked for solutions on the web - none seem to fit my problem exactly.

Can anyone please help me?
