hi hal,

i was gonna send you the diff for that... but you already found the
solution... still interested ?
i'm not sure whereas we'll commit that. i need some other's opinions.
I recall some comments on the behaviour of the previous button. It can be
very tricky coz if you take the processpanel for example you don't want to
execute the processes twice.
adding the listener is a good idea... just gotta find a suitable solution.
for your personal work i can send you the diff.
