[PD] gem live-video input

Hey all,

If I try to position my window on my 2nd screen - it doesn't let me 
create a window. I succeeded once, while fooling the window, by changing 
the arrangement of my 2nd screen while the window already was created. 
Once the 2nd screen is detected and you change the offset message, the 
window doesn't create anymore. [see output below : unable to accelerate 
window that spans multiple devices]

Also - maybe it's normal - the Gemwin doesn't react instantly on the 
messages, you first have to destroy the window, then press each of the 
messages and then you can create the window with the custom 
size/position you want.

I never worked with gem before, so excuse if questions are really dumb.
