MS Office 2003, Windows XP Home
This just started happening today...until now Excel has worked fine.
If I try to bold, underline or italicize text the program hangs. I
have uninstalled and reinstalled Office, done the updates. Very
strange. As far as I can tell, all other functions work, include those
on the formatting bar. If I use the Format on top toolbar, I get the
formatting dialog box but then the app hangs. The only related thing I
can find on the web is people who cannot open or save documents, but I
have no problem with that. When the Microsoft Report Error screen
comes up, the technical details are two files:

C:\DOCUME~1\User1\LOCALS~1\Temp\WERcaea.dir00\EXCE L.EXE.mdmp
C:\DOCUME~1\User1\LOCALS~1\Temp\WERcaea.dir00\appc ompat.txt

I have ran Detect and Repair as well. The Event Viewer simply shows
Application Hang, with no help. I have no idea what to do next. Any
help would be appreciated.
