You have too many files open at one time. I run Win98SE and ALSO run
Office 2000 just fine.

Scroll back up the Community Newsgroups list to Office (for an Office
program problem), Home Productivity (for an MS Works or Money problem)
or Internet Technologies (for an IE/OE problem). Click it and then find
the appropriate newsgroup to post to--that's where you will find experts
on the program you have a question about.
