Seems like this may be more a problem with scrolling panes than with format-graph-from-roots. Previously, I incorrectly reported that I was having trouble with the built-in graph types, but not with my own. That was wrong --- it seemed to be true only because my graphs were smaller. So it now seems that the problem arises with any graph that is installed inside an application pane with :scroll-bars :both. Has anyone else seen problems with scrolling application panes, either especially with graphs in them or just in general? I am starting to suspect that my change-space-requirements fu is weak.... thanks, R
