[racket] slow response in DrR 5.2.1

We've got a couple of Windows labs with DrRacket 5.2.1 installed, and we're seeing really terrible response times: with a fairly short, simple graphics program (using the picturing-programs library) operating on small images, we click "run" and wait 20-30 seconds for a response.

I'm not actually teaching a Racket-based class in those labs this semester, so I haven't taken the time to track this down to specific examples, nor tried installing 5.3 to see if the problem goes away.  But is there a known performance or installation problem that would cause this?
