Re the error message
"There is insufficient memory or disk space. Word cannot display the requested font."
I finally how found a way to fix problem, albeit temporarily, without having to reboot, repair Word and various other suggestions.
After deleting normal.dot... if I then run "Smart Defrag 5" then click "Smart Optimize" the error then goes away, for a while, but at least I can print Word Docs now, which is a relief.
If I could fix problem without having to run "Smart Defrag 5" a couple of times a day, that would be even better.
