Thanks Kim.  I compiled a CVS version 22.0.50.1, and indeed the problem
seems to have been solved (with about 3 hours of similar testing down).

Can you think of a reason that my mode might trigger the bug more
often?  If possible, I'd love to work around it, so that Emacs 21.X
running IDLWAVE wouldn't suffer from it.  Or is it really a generic
re-display issue that cannot be easily avoided?

Thanks again,

JD
