When I go into the Options -> Display menu, and change my resolution, I get a black screen. When I press escape I'm shown the Main Menu with the new resolution. This is not really harmful but just a little confusing to the user...
HmmI'll try to reproduce this... are you playing full screen or windowed?Also, there seem to be a lot of bugs in the display setting on the windows version (it works, but you have to reload the level to get the textures back).
Oh, nevermind, I see what you're saying. It's not going back to the menu if you don't have a game loaded. Fixed in SVN.
