I have the same exact problem as TheFieryFox. The crux is that it also does it with the trainer from cheathappens for Sumpreme Commander Forged Alliance.
I found out the reason why the trainer hiccups. It seems that if the explorer shell in Windows crashes and restarts that the trainers will start with the strange behavior. Just reboot Windows and the trainers should be fine. At least that's how it is for me.
