I've got two Dell netbooks that can both play the game just fine. But the screens are so small the entire upper half of the window is gone, making it impossible to check friends and access the menus. The options screen is likewise all screwed up, the picture is in the right place, but you have to click 5 inches above each item to actually select it, and the drop down menus are all blank. I tried the fullscreen thing in the technical support sticky, but they don't have the HKEY_CURRENT_USER\Software\JavaSoft\Prefs\projectx part. I don't know of any other way to fix this, but it's pretty well impossible to play without fixing it. Any help would be appreciated.
You've started the game and there's no key yet? That's odd, the moment you set a custom option it should be there. Even if you just log on there should be at least one value in the key.
