You could also check the config.wtf file for that character I suppose. ISBoxer keep individual ones for each character in your WTF folder. Open the file in notepad and look for a line saying: "SET gxFullscreenResolution". I had some random issues where clients were launching at odd resolutions and changing it in the WTF seemed to fix it for me. So for example most of mine say: SET gxFullscreenResolution "1920x1080".
