I wish new Windows versions had such great compatibilities with older programs.

Anyway, I think it's weird that JJ2's title bar doesn't get the XP theme (at least not for me) which sucks if you try to click its title bar buttons: XP's (themeless) buttons are thinner and they only become visible over the 'traditionally big' JJ2 title bar buttons when you click them. So I have to click the left part of the maximize button to minimize JJ2, which I happen to forget all the time.
