> So far no luck in reproducing this outside of our product. We have a GEF based view, with some drawn canvas on the left and a property page on the right. Clicking on an editable cell in the property page opens an editor. From that point on we see endless calls to Tree.rendererGetPreferredWidthProc.
> This results in an endless wait in a few of our ARTs, which wait on display events and jobs after clicking on a cell in order to edit it.
