Hi Jayden56,
no, I try command+shift+3 or command+shift+4 and the Grab App.
I'm running a Mac OS X 10.6 Server guest, with a Mac OS X 10.7 guest every thing works well, I get a screenshot.
An old Mac OS X 10.5 Server guest, running on Fusion 3.1.4, works well too.
I can't take a screenshot from my Mac OS X 10.6 Server guest only.
Sorry,
Lutz
p.s.
The VMware Tools are up-to-date.
