I cannot see the numbers after clicking on the button (I'm running on perl 5.8.8 under MacOSX).

However, when I run it under windows xp on activestate perl (5.8.7 build813) it works fine.

I wrestled with this issue a while ago, but can't quickly find the solution. I'll update this if I find it.

UPDATE:
Ahhh, zentara beats me to it...well done! His solution is what I ended up doing too. See, this proves that great minds, and little-teeny minds (me) sometimes think alike too.
