Shortcut Conflict

Do you use RegisterHotKey in exe? If the target window used it first, your RegisterHotKey will fail (return 0). If you use it first, the target window will fail to register it. If the target window uses some other method to intercept the hotkey, then your RegisterHotKey will succed, but if your macro presses F4, it will be triggered itself. In either case, if you need F4 trigger, use low level keyboard hook instead of RegisterHotKey.
