What I would like is a list of checkboxes (and, in a few other frames, several buttons); if a scrollable frame were available in tkinter, I'd use that. While canvas is powerful, its power is not needed for my purposes. > > Saul -- http://gall.mine.nu free to get comics,free chat-1,dc++ (dcplusplus), mute webcache,group update program,torrent,atomic time server,tool to find your ip -- http://mail.python.org/mailman/listinfo/python-list
