using current GW8 Client have a reproducable problem.

Take 2 (or more) computers and let them use the same Groupwise Account:

One screen will refresh screen contents (e.g. new mail, deleted mail),
while the other one wont refresh its content. Set the autorefresh on
both machines to one minute, but even if wait longer (e.g. 5 minutes)
the content of the second screen wont refresh until I press F5.

I tried this with different GW Users on different computers, so this is
a real GW Client fault, I think.

Using Groupwise 7 Client works without problems.
