[racket-dev] Seg fault

Similar crash I've run into
(on my Windows XP Prof 32 bit virtual machine).
Holding the upper right corner of the DrRacket window with left
mouse press I've done some mouse moves to change its size.

Result:

Unhandled exception at 0x68de6fd9 in DrRacket.exe: 0xC0000005: Access 
violation writing location 0x36163378.
