Well it works perfect with another project I made being able to go to fullscreen in with all the different setting although I keep getting errors on the platformer I'm working on when compiling. I wish it told me what I did wrong. For another topic I suppose. I still find it perplexing why I can't full screen properly in flash as each project seems to have different results despite what the settings are.
Edit: oh my god, I just found out the flash fullscreen settings are linked to the web settings. I've been trying to change it via the desktop settings the entire time. You could not possibly fathom how dumb I feel right now.
Edit again: Forgot to thank you for your time and help, so thank you
