Oks here is a zip of the player, implied and target xml , straight out of the UI file that I am using in game.... They work at my 1280 and the windowed mode of the game is 1024 and they work like that also (well for me at least hehe)
Thanks for sticking with me on this, Fingers crossed those ones should work for you also...
As a thought your not testing monitors to destruction at the moment are you ? and maybe you plugged the wrong one in hehehe
j/k
