That would definitely solve the problem. Another commenter recommended I try window locking the mouse, so I'll probably experiment with that first since I wouldn't want the box to be too small. I'm surprised you had good things to say about the style, I haphazardly tossed this together in a way that would make a real artist cry if they saw me mid development, so it's nice to know the final product was at least on the right track. Thanks.
