[PD] gem live-video input

[roc]

by the way, i recently got gem 0.90 and i cannot get video input 
anymore.
for some reason i just get a green screen and sometimes a couple of 
lovely big-ass squares on the gem screen. then nothing.
i'm on os x.3.7 pd 0.38
webcam is a logitech pro. used to work before with gem and the hardware 
is still ok.
ideas?
