I have read a few topics about GameEx doing weird things with resolution after playing MAME games. I am still experiencing a problem, but not sure what I'm seeing matches the other posts. I am using BlueEx 640 x 480, my screen resolution is set to the same. After playing a game like "Donkey Kong 3 " (this is just one example), the font in GameEx is much bigger. It is funny but it does not occur with all games (from what I can see right now). If I switch to the 800 x 600 version of the theme, my fonts look okay, but not displayed in the same spot (looks shifted to the right). Unfortunately, I can't find any real pattern and to make things worse, the bug does not happen every time. This does not occur on any other emulators, just MAME. I tried a few other themes and didn't see this happen. I can troubleshoot or send over anything you need. Hope it was okay creating a new post for this -- I wasn't sure if this is the same issue as others have reported, or what has been reported as being fixed in the last few releases. Thanks Tom!
