The steam version of codename gordon (cg.exe) creates a separate exe in the users temp folder, this exe is just macromedia flash player 7 and doesn't have the 640x480 fullscreen lock and also allows for easy resize clipping. This version can be from downloaded here: https://drive.google.com/file/d/17xBks5Hxzqg9gjdpUwoPz1RaFEkolI6L/view?usp=sharing

Thanks for the info! :)
