Hi Nikoloai,
I have a problem like that you described. I don't know if your problem was the TCL interpreter.
I am not using any TCL interpreter and I have the same annoying windows.
Moreover, I had an application whithout threads management running well and, when I programmed threads, the console begans to appear.
I think then that our problem is based on threads, on something that we are doing wrong.
Have you encountered the solution to your problem?, or in general, has anybody an idea about what is happening?
Best regards,
silmarba.
