Setting new game resolution doesn't work as expected

[swordmaster2k]

I'm trying to change the resolution in the *.game file. when I change it and rerun the game, the window doesn't appear to be set to the size of the resolution. currently there's no board or startup program. I expected to be able to change resolution, run game, and see the full area of the resolution in the window. what I'm observing is, if I set the resolution to something like 800x600, save, and restart the game, the window is the 640x480 size and I have to manually resize the window (till the scroll bars disappear).

Have to restart the editor for it to take effect.
