Well, you don't seem to understand. You say, "If I touch ANYTHING in the
A-Talk III menus .. none of .... will work right". This is FALSE. The cursor 
and keypad keys are reset in ONLY TWO conditions:  change font and resize the 
window (and change the terminal type if you wish :-)  None of the other menu 
selections has any effect on the cursor and keypad keys.  Of course, logging
into a system from the Phonebook will also reinitialize the terminal to
the RESET condition of whatever terminal you've chosen (VT100, VT52, H19, etc.)

Note that the keypad and cursor key STATUS are NOT saved when you save
a phonebook entry. This is exactly like on a REAL VT100, which will start
in its RESET mode when is powered up.  There are quite a number of programs 
that ASSUME that a VT100 is set up in such a way.

Good luck at finding another terminal program that does dynamic-VT100 
emulation in a Workbench Window.
