This is a known bug to ParcPlace Systems, the developer of Smalltalk 80.
(They claim that this won't happen in Version 4.0, though I haven't tried
it out.)  If you still want to hang around with Version 2.5 for some
longer time, their suggestion is to start Smalltalk using the following
script.  (I got this script from a ParcPlace technical support engineer.)

st80 $* &               # essential to run st80 in background
exec > /dev/null 2>&1   # suppress silly warning messages
while kill -IO $!       # repeat until you quit from st80
do
	sleep 5         # kick every 5 seconds
done

Hope this helps!
