Indeed, I forgot that. The following output was generated with DrRacket 5.1.1 in Window 7 while moving the slider from 0 to 4. The extra callback calls are generated when the mouse button is released. slider@-469734252: 0 slider@-469729961: 1 slider@-469729750: 2 slider@-469729177: 3 slider@-469728498: 4 slider@-469727374: 4 slider@-469727374: 4 Just clicking the slider (without moving it) also causes two unnecessary callback calls. Thanks, António Leitão. _________________________________________________ For list-related administrative tasks: http://lists.racket-lang.org/listinfo/users
