which I couldn't do w/ Win7-Pro within VirtualBox (2 Monitors),
ie say the primary shall be the 'right' monitor.
But thats probably a VirtualBox driver problem.

Yup. Guess we need both:
- Allow negative coords to allow 'spanning' to another 'Screen'
- If not using the 'default' Screen in Window, figure out the proper coordinates
Will do that soon ..
As it stands, we have a few bugs left in Mac OS X (AMD GPU & Some crashes),
