MabiPro: The Authentic Old-School Mabinogi Experience

This is probably a long shot, but I play official Mabi from time to time and when I log on I have the resolution set to 1440x900, and since MabiPro doesn't have the other resolutions and they share a documents folder, my MabiPro window is 800x600, no big deal I'll just resize the window to fullscreen, but when I get back on official, the resolution of official is 800x600 aswell, and then all my windows are messed up and I have to restart the client to get it back to 1440x900, since I don't play in border-less fullscreen. I was wondering if there was a way to implement extra resolutions, in particular, the ones that are used in official? It's fine either way, great work, keep it up!

Just curious, why not play in borderless fullscreen? Normal fullscreen has that godawful glitch where if you alt-tab, you're far more likely to get a grey screen when you return to game, as in your graphics on the game break. There are programs out there to force borderless fullscreen, one which i use for mabipro. So again, just curious why you don't want borderless fullscreen.

Borderless fulscreen doesn't actually change the resolution....
