I don't know why did this start to happen, but one thing that's certain, it did.
Whenever the game turned back into full screen, the text on most menus became garbled and corrupted.
Last time this occurred, i was eventing some brick to test out a new sound, but before i can even finish, the event menu became unresponsive, and then the above started happening again.
I have the console log posted, hopefully this will help.
