Thanks; ScrolledFrame (and the rest of Pmw) looks very useful, and I'll be
experimenting with it in mere moments.

Would you mind telling me what you used for a reference to find info on
winfo_height() and update()?  Did you just install and read through the
Tcl/Tk docs, or is there a particular book you like?  I like PP2E over
all, but the index leaves a little to be desired.
