I see that `get-scroll-range' fails for a canvas or scroll direction for which scrollbars are not enabled. I'll fix that. > - More importantly in version 5.3 what happened to mrtabgroup ??? > How do I create tabs? Do you mean "mred/private/mrtablegroup.rkt"? It was an empty module in v5.2.1, and we removed it in v5.3. The `tab-panel%' class is still available, though. ____________________ Racket Users list: http://lists.racket-lang.org/users
