Auto scaling: All user controls should have AutoScaleMode set to Inherit (i.e. they inherit their containing form's AutoScaleMode, in this case Font). Explicitly setting an AutoScaleMode on user controls causes problems with child controls anchored to the bottom and/or right.
Remove explicitly set font in GenGameGenie form. Fonts set on the form/user control level cause problems with auto scaling.
Fix text box anchoring in DualGBFileSelector control.
