Bill - thanks for your reply. You're probably right but I was hoping to avoid diving into the viewmat code. I have been looking at the "platimg" library to see if that offers any hope but, since the problem apparently has to do with how events are handled, I'm not too optimistic. As a workaround, I have a piece of code to generate statements that I can cut-and-paste into a session window - this works, it's just klugy.
I'll let you know if I find something else. In the meantime, you could see what I've been up to, if you're interested, by taking a look the "algorithmic art" I've been doing with J at my flickr site: http://www.flickr.com/photos/photonatic/sets/72157600280547434/ .
