Sorry if this has been covered, but: Togl does not come with Tc/Tk (or 
did not when I installed). Go here if this might be your problem:

    http://togl.sourceforge.net/

Pretty amazing install/build instructions, IIRC.

The acid test on many questions you might have is: Can you do it from 
wish? ie, run wish.exe and try XXXX manually or by using a Tcl script 
provided by the folks offering XXXX. When /that/ works you can focus 
debugging on Celtk. (I am not discouraging questions, just sharing with 
you my own attack sequence on some problems; it is really nice being 
able to hop over to wish to do a sanity check before staring longer at a 
Celtk problem).
