activation decay between events (leabra++)

[Matthijs van der Meer <M.vanderMeer@ed.ac.uk>]

Dear PDP people,

I'm having trouble getting a particular leabra hidden layer to preserve
its activation between events. Setting the events.decay parameter in the
.specs to 0 (from the default 1) does not change anything. I've also
tried changing this parameter from a script, but it has the same lack of
effect.

Am I overlooking some other process/event/gotcha that somehow resets the
hidden layer's activation? 

(I'm using the "pt" project included in the simulations discussed in
"Computational Explorations in Cognitive Neuroscience" by O'Reilly and
Munakata (2000))

Any clues would be greatly appreciated!
