I tried your code on a Unix machine (Solaris) and it worked just fine.

I tried it on my Windows XP machine, and it did not work fine.

Perhaps it is because Tk calls the native messageBox?? and Windows is more restrictive??

Interesting note: According to the docs, -font is not a valid option for messageBox, so it suprises me that it works on Unix.
