Do you use these options as described in the readme/instructions?
Ah thanks for that yeah just realised it was a png.
Just tried that and unfortunately not working.
1366x768 down to 800x600. had closed the trainer, ran again, and still same no maximize, stays stuck on task-bar and thumbnail/preview is the same.
Put it back to recommended for the laptop 1366x768 an no change either.
Trainer still works in any event.
