Zentara, thanks.
But it appears to me your solution is using the Tk interface rather than the Tkx, so my question is which do you like better and why? I did start with the Tk interface and moved to the Tkx because having the latest Tcl/Tk engines. Not to mention that the GUI had the themed widgets which of course looks more current on WINDOWS. But, I am beginning to re-think my decision... any advice?
