Edit: I moved all these posts around and then realized that it is working in Windows 2000 because pagalzone posted about the cross (X) button not working.
It crashed.
Does it just crash when you enter chart mode? Or only sometimes?
It is because it is not supported. Only XP, Vista, 7 are supported.
It's true that I say this, but it might/should work on Windows 2000. I'm not running a Windows 2000 machine and cannot test this, but it appears that it does, at least partially.
