If you put the cursor on a stack of cards and then depress the delete key (press and KEEP depressed) then ZunTzu crashes with the following error:

Actually Windows 7 also has the problem, so it must be a bug in ZT generally.
It seems to happen when you zoom close to a stack of cards (or a counter on a countersheet with a large "supply" quantity) and press the space/delete key.
Zooming in causes the fans on my system to rev up substantially (and my lower powered laptop slows to a crawl), so I'm presuming it's some fault with the graphics engine.
I'm surmising that ZunTzu gets overloaded while attempting to visualize each and every card/counter in a stack, even though this is unnecessary...?
