I'm running the same thing but without the mac spoofer...
And no one else has mentioned anything :s
Is "L+>" set as your nitePR screenshot key? might be freezing you?
:s
Is everything in the right place?
Cause im running 3.90m33-3 too, and its 100% fine...
Um, try to wait a bit before you turn it on to when the game isnt loading a lot of info or something.... :s
