There's another thing i should tell you guys.  Every single time that i close stk since .7.3 RC1, stk has crashed on exit.  That means that i click the exit button and bang!, it just crashes.  I've got this terrible feeling that opengl isn't being closed out properly and that system memory is being wasted.  Incase you need it, my os is Windows XP and of course i have the latest version of stk.  I'd be a bit happier if this wasn't happening, maybe i have no cause to worry? :)  Anyway as always it would be a good thing to get fixed.
