I just told our Mac test group that they could try the new GroupWise
Messenger client for Mac OS X (the new sp2 one). I had tested it on my Mac
running Mac OS X 10.3 and it worked fine, so I know it's probably not a
server issue. When they try to start it, they say that it just won't start.
They don't get an error message or anything. They are also running Mac OS X
10.3 and their machines have been kept up to date.

Does anyone have any suggestions on how I can troubleshoot this? Is there
some prerequisites that I should look for on their workstations or
something? I didn't see anything in the readme for the client.
