in thread Running a threaded Tk script on Windows

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).

    Well, I rewrote a Windows version which loads and starts the threads before I require any Tk modules, and it still fails. It just brings back all the nightmares which made me dump Windows to begin with. Screw Windows!! ;-)

    • Don't load stuff, particularly stuff with XS elements, prior to creating threads that do not use that stuff. Specifically, loading (useing) Tk; means that pats of it will be loaded into multiple threads regardless that it is not used in them all. Thins is a recipe for problems.
    • Don't port code, especially threaded code) to Windows ME first. Use NT/2K/XP and then backport to ME (if all your attempts to avoid doing so fail).

      The "good enough" maybe good enough for the now, and perfection maybe unobtainable, but that should not preclude us from striving for perfection, when time, circumstance or desire allow.

        Well to trace down the problem, I stripped out all Tk code, and the problem is in the creation of the shared variables. I will post another question with a minimal example, using no XS.

        Well, Me is all I have, and I simply refuse to feed the "beast from Redmond" anymore.
