I don't know if this is the case here or not, but putting in scrollbars and= scrolling can be a bit tricky. It usually works best to create the canvas= without a scroll command, then create the scrollbar(s), then use tkconfig = to go back and add the scroll command to the canvas after the scrollbar has= been created and placed.
Hope this helps, -- Gregory (Greg) L.
