WinXP: Changing the background of the canvas (edit pd.tk line 82: set canvas_fill #FF7F00) doesn't make the object visible. Also I can make a line appear when I move to join two toggles for instance, but the input of the second toggle won't accept the line.
Maybe it accepts the line while making it disappear. It has to do with how that line is drawn: usually, the visual line you drag is deleted when the internal connection is made, and then it is redrawn using the same code that draws lines when opening a patch.
With all that has been said, what looks broken is the procedure for triggering redraws. You can figure out whether it is it, or an untrapped tcl/tk problem, by inserting fprintf(stderr,...) in the draw-methods to see whether they are called or not.
