Thanks for the ideas. But I do spawn the threads before I start any Tk code, and it does run fine on linux.
Just because it works on linux doesn't mean its supposed to :) and the mere act of useing the module executes code. From perlthrtut
If you're using a module that's not thread-safe for some reason, you can protect yourself by using it from one, and only one thread at all. If you need multiple threads to access such a module, you can use semaphores and lots of programming discipline to control access to it.
Tk is not thread-safe.

I run a Win32 PPM repository for perl 5.6.x and 5.8.x -- I take requests (README).
