[racket] DrRacket Crashes?

Hi, DrRacket is crashing while I am using this code (from 'picturing
programs'):

(require picturing-programs)

(big-bang (overlay pic:calendar (rectangle 100 100 "solid" "white"))
(on-draw show-it) (on-tick rotate-cw 1/2))

To reproduce:

1. Start Dr. Racket
2. Paste the above code in the definitions pane
3. Press CTRL+R
4. Left-click the 'x' to close the resulting animation window
5. Press CTRL+R



I'm using Dr. Racket 5.3 on Win 7 64-bit.
