I just got dual CRT's working with twinview, and this has brought up a lot of strange issues with cedega(4.0-1). The only two programs I currently run under cedega are Battlefield 1942 and Half Life, so these may be fairly localized problems.

Battlefield 1942 will run ok whenever cedega allows it to go full screen, although it does not detect any available resolutions above 800x600, (both monitors are working at 1280x1024) and does not take up the entire screen...it will take up its 800x600 square and leave the rest of the space on both monitors black. I adjusted the config file to force it into a window, and now everything would be ok but the mouse is wild and uncontrollable. I turned off the Direct X mouse grab to see what that would do, and it just throws my pointer to a random position outside of the program. (I also tried running Maple 9 out of cedega at one point, back when I only had one screen, and had issues with the mouse there as well--it just dissappeared anytime it was over maple's window.)

Half life will not get to the first screen. It calls up the console as if to report an error, then just hangs. Both games worked nearly flawlessly before switching to dual monitors.

An additional problem, this one not concerning cedega though, is mplayer. The media windows no longer have a title bar with which to move them. They simply start in the upper left corner, and I can't find a way to move them. They can still be resized.

If anyone has any suggestions for any of the several problems mentioned here, they would be greatly appreciated.

I fixed the mplayer problem with the geometry option, and half life started working as well. I still do not know why battlefield only sees 800 x 600 though, and I still have problems with the mouse with any windowed cedega app.
