I don't know if anyone else has this issue but it doesn't seem to save it's config/location, because I'm forever turning windowed mode on and every time I restart the game it still goes into 800x600 fullscreen, and even when I do window it it goes up to the top left of my screen and takes me over 100 click attempts to drag it to the center. It's really starting to aggrevate me.
I dont think there's any fix for this, as it was just like this in GMS too. Starting it up it always opens in full screen- just hit "Alt + Enter" when you hit the login screen.
Try something called DxWND it then can launch it for you in windowed mode all the time http://lmgtfy.com/?q=dxwnd
Thank you very much I used to use this back in gms but I couldn't rememebr the name for the life of me.
You are very welcome my friend if you have anything else in need let me know and ill try think of the best solution
