Groupwise email Freeze!

When installing new users in the Novell environment and then adding the client for Groupwise and Groupwise, the attempts to read mail freezes the groupwise process. This seems to happen on some workstations and not others. I have been told that this sometimes relates to Office 2000 applications. I have uninstalled all of office (and others) and still have this problem with groupwise not installing properly and or not being able to get to email without freezing. Does anyone have any remediesfor this problem?
