Hi all,

I am playing with highlighting edges (par of an arrow shape) by expanding their width, but I have found that when un-highlighting by contracting their width nothing happens. I have the code below:

lastview is the view, edge is the compound shape of the edge and the arrowhead, highedge is the highlighted edge, if any.

highlightEdge: aName |edge| edge := lastview edgeFromModel: aName. edge isNil ifFalse: [ highedge isNil ifFalse: [ highedge shape shape1 width: 1. highedge update.]. highedge := edge. edge shape shape1 width: 3. edge update. lastview signalUpdate.]

With this code, thickened edges (width: 3) stay thick, even when made thin (width: 1). I suppose this is a bug. If not, how can I get the behavior that I want?

Thanks in advance,
