To be honnest I do not call any Tk lib. I even do not know why it appears in the stack ...
My C code uses wxWidgets lib for the GUI, hence the Perl side is used only for computation or some lowlevel accesses...

You are aware that Tk is not thread safe? Of course that may not be your problem, but it is a pretty good candidate. In fact Tk can be used in a threaded Perl program, but it must be done with great care. HTH -- Brian Raven This e-mail may contain confidential and/or privileged information.
