We have GW Client 8.0.1 and are experiencing tones of issues.

The Setting:
On brand new fresh installs of WinXP with sp3 and GW8 sp1 Client

The Problems...
1. Most stations lock when starting the GW client...
If I set the icon compatibility to Windows 98 then it will launch, but I have several issues with the client. Some issues are, you can't open attachments unless you choose the "Open With" feature. If I don't then the attachment will crash the Client or start running Microsoft Office Setup .. all kinds of weird things happen.

2. I have noticed if I use the Windows 7 OS, then the problems go away.

Does anyone have a fix for these issues, it has put our GroupWise in a serious state.
