I have already "solved" my problem, but I am hoping someone can shed some light on what happened.
If I don't get any responses, I will PAQ this problem tomorrow.
The problem: whenever I close a word document I use Alt F C it does not work and gives an error message
"this command is not available on this platform"
I tried disabling all macros, and deleting Normal.Dot and Normal.dotm but that did not work.
I logged mydomain\rberke off, then back on. Alt F C still does not work.
I tried disabling the Dragon Naturally Speaking addin. Alt F C still does not work.
I logged rberke off and logged on as cpuxxx\adminstrator. Alt F C now works.
I loggoff and logged on as Mydomain\rberke and alt F C now works -- even after macros and Dragon were reenabled, and Normal.Dot & .dotm were restored.
So, things were "solved" but I can't really say why.
Other miscellaneous observations that may not be related to the solution.
When I first opened Word as administrator Word 2010 offered to configure itself for
automatic updates. I said yes, but I was surprised by the question because my rberke login was already configured that way. I then performed a Windows Update, but Windows Defender was the only important update needed. I installed it, before logging out of Adminstrator.
I use office 2010 32 bit pro under windows 7 64 bit pro.
Other addins like Snagit, Scansoft, Pdf Converter etc were never changed.
