Ok, for anyone interested it felt bad to do to tkinter but even more importantly, it was not necessary to be so wasteful with threads, I really only need a single GUI thread (I may not feel that way the first time a problem in one window hangs them all), so I just redid things so all the windows are created and controlled by a single thread, and I use a list as a queue of commands from other threads (i.e. "open another set of windows associated to xyz data").<BR>

cheers.<BR>

As I"m just hacking this together (the pretty Tk interface is an addition, not really required to be build) to do this I call the master object which is a threading object... i.e. another thread is started, and this other thread has a mainloop call in it. It all works fine, but I'm sort of of the impression I'm not supposed to do this, that there should only be one thread running a mainloop call. </FONT><BR>
