No, that is how Windows works. If another program or the Windows Desktop get the 'focus' by clicking or Alt-Tabbing to them, then fullscreen programs, like games will minimize.
TouchBuddy gets around this by having special code that does not allow it to ever receive the focus. You can click on a TB button and it will click it, but it does not receive the Windows focus as the current program, so the game keeps the focus and does not minimize.
But you can use TB for lot's of things. You could make a profile that displays a web page and use it as a web browser, then you can browse the net and not minimize your game. You can use it to display Word, Excel, documents, Images, anything a web browser can display....
