Hi folks,
Just adding my vote for better dual (or multi) monitor support in version 5.
I have one monitor in landscape mode, the other in portrait mode. Both are LCDs so changing the resolution is not really an option, nor a desire. I use one monitor for editing videos and landscape pictures, with the the toolbars, control panels, etc on the second monitor. If I am editing a portrait then of course it is reversed. I have been using Google's photo screen saver, it is seems to handle my dual monitors ok. I will look and see if it was an open source project if that would help any.
