We're running GW 8.0 SP1 installed via the msi downloaded from Novell's
website. I've had a few users who has reported that they've been unable
to use the delete key. Not every time, but occasionally. It seems like
it doesn't work anywhere in GroupWise (i.e. while you're typing, or
trying to delete an e-mail)

Happens in both online mode and caching mode.

Any ideas?
