IanP, that is very interesting. I have attempted to set the pop-up screen positions and sizes in the panel.cfg but was unable to do it properly. There is also a problem with the panel sizes changing when you go from full screen mode to windowed mode and back again. When I looked at the SDK I couldn't find the relevant info.
This is also coupled with a problem in Windows 7 (and maybe XP) when running multiple monitors with AMD's Eyefinity product. I want 3 Eyefinity grouped monitors off an HD5850 video card and 1 or 2 other monitors driven by a 2nd 5850. All the monitors are the same model. I can position the monitors in the Windows display control panel or in the Catalyst control panel but the positions and even the resolutions of the 4th and/or 5th monitors change back to some other setting when I reboot Windows. And the resolutions are put into some not native value. However if I ungroup the monitors then Windows seems able to remember the positions/resolutions.
This is occurring in three different computers.
