Indirectly also causes the mouse capture API to scale incorrectly. (The more you move it down, the less of the bottom half of the window you can navigate with.)

Current workaround(s);
-Use my keyboard to change the resolution in settings, by changing the resolution to a different one, then to the desired one to force a redraw.

-Make a guess at how big the window was. Doesn't always work.

Suggested Course of Action:
Do not allow resizing of the window. In the off chance that a window is resized, write Win32 api code that causes the 2nd button (resize button) to allow a user to force a redraw of the window size to it's correct dimensions.
