changing resolution in game

Not sure if it's a bug but here goes nothing.

Basicly what happened is i changed my resolution and my game went black (all i was seeing was a black screen) and i was therefore unable to change it back. A quick and easy solution to make sure it never happen again would be for you to implement a timer that if you dont press an ok button after switching the resolution it change it back to the previous one. That would make sure that you agree and are ok with the changes.
