In addition to the other questions, and if you're using plain Racket instead of DrRacket: What version of Racket are you using and on which platform? There's sometimes a problem with Racket's default stack reporting in v5.3.6 and earlier, especially on 64-bit platforms. Using a snapshot from http://www.cs.utah.edu/plt/snapshots/ http://plt.eecs.northwestern.edu/snapshots/ might help, in that case. ____________________ Racket Users list: http://lists.racket-lang.org/users
