some users have random errors while using Groupwise.
All machines are running Windows XP SP3 and Groupwise 8.0.1 Build 88138.

User A:

GroupWise crashes on the very first email sent. After running the client again the issue is resolved. Error code in the Windows event log:

Faulting application grpwise.exe, version, faulting module grpwise.exe, version, fault address 0x000d480a.

User B:

GroupWise crashes sporadically while working on a Word document or using IE 8.
Only error given is the "Do you want to report this to Microsoft" window.

User C:

GroupWise crashes when an external message is opened. Event log has the following:

Faulting application grpwise.exe, version, faulting module unknown, version, fault address 0x06272420.

Had other reports of GroupWise crashing without any warning or error messages, but no logs to add.

It's quite unpredictable and except for the first issue not recollectable.

Anyone with similar issues (and possibly solutions) that might give me an idea where to start searching?
