[linux-audio-user] is this a bug?

As discussed in the thread earlier today ( using jack-rack as real time effects processor ), i am, er, using jack-rack as real time effects processor. Anyway, I have hit upon some behaviour that doesn't seem right to me. I am putting some pretty heavy artillery ( basically some drums and a bassline ) through jack-rack and the compressor that shows up as "SC1" ( is this one of Steve's? I can't remeber ). Everything is fine until I drop most of the input out, and then the compression just stops working until I reload the plugin. Clicking 'enable' on and off doesn't work. Anyone know what is going on here? Thanks, J.
