When I use alt+enter to switch to fullscreen the current image of the game becomes fullscreen but it does not move or anything, the game is still running and is responsive to input, but the fullscreen image appears still. As well as this I am unable to 2x the window and I can only use a limited variety of window sizes. I use 640x480 VGA currently, all other screen sizes appear smaller or report an error when I restart the game such as "You do not have the proper drivers, reverting to previous settings" and revert to my previous settings. Please help and thanks for looking into this

Move the game out of 'program files' and then go to Base.rte/Settings.ini and edit x&y, but you can only get fullscreen with original resolutions, so just make the window the size of your screen.

Full screen is rather buggy. Have you got the same problems as stated in this thread?

Thanks guys your suggestion of taking it out of program files worked great! Fullscreen and 2x screen wont work but I can freely change the size of the window now which is awesome!
