I really need somebody to address this issue. I too am finding the same problem. While I'm at the castle and go into the "dream world", it is impossible to bypass the stuns, even catching on fire from one of the fire demons. I'm constantly on fire!
SOMEONE...anyone???? Any suggestions as the previous posters are saying what's going on, but it's not being addressed.
Happened to me once; I think it was because I hit the ' key when I was ,alt-tabbed. I just switched characters, disabled infinite health trained some baddies into the stunned person and let them die. Then saved game, exited the trainer, exited the game, then reloaded the game and the trainer and everything worked fine.
