we are using dr Scheme v4.2 (I know its an old version but the tech guys at my school take months to test every upgrade that we ask for) and we are running windows 7.
Tangential question: How many instructors have students stuck with old versions of Racket because their school computer labs are not able to install recent versions often, for whatever reason? (Erwin, you are not alone in this problem.)
I'm wondering, if the students need to use lab computers rather than their own computers, whether there's a real need for a bootable version of DrRacket on little USB flash drives. So, if the lab PCs permitted USB booting, the students pop in their flash stick, reboot, and they run an entire OS and Racket setup, with their assignments data, all stored entirely on the flash stick alone (not touching the PC's hard drive). When they're done with their lab session, they remove the stick and reboot back to the PC's normal configuration. I have made a more complicated version of such a thing before ("http://www.neilvandyke.org/lildeb/";), and I could probably find time to tailor a simpler one for DrRacket, if there is a real need for such a thing. I estimate that the sticks would only need to be about 512MB in size. (The local store was giving away sticks 4 times that size, for free, just the other day.)
