|I don't have ATalk, so I can't tell what it is doing, but I did write
|MyMenu.  It looks suspiciously like Workbench is getting a NEWPREFS(?)

|menus (other than waiting a second or two).
|Best bet is to find out if ATalk is indeed sending a NEWPREFS (such as
					    ^^^^^^^^^^^^^^^^^^
|changing serial parameters) when it starts up or exits, and find out if
|it can be disabled.  (Probably unlikely, but it may be slightly possible
           ^^^^^^^^
|that if serial preferences are exactly what ATalk wants, it may not do
|the NEWPREFS)

A-Talk III calls GetPrefs at loading time (to get parameters such as RTS/CTS,
Xon-Xoff or no handshake, and to 'save' the current preferences). It also
calls SetPrefs on exit (to restore WB colors and other saved Prefs parameters).
Neither one can be disabled.  As implemented, Mymenu is a kludge that can't be
supported. It munges data structures that shouldn't be touched, and as such 
can have the 'side effects' you experience. Since other programs do
the GetPrefs/SetPrefs combo, the problem won't appear with just A-Talk.  Maybe
a better version of MyMenu could be written.
