Sridhar,

This means we need to proceed with an OS.* calls test.
Steve:  you have a pile of those in your image, could you share one?

P.S.: Drawing to Canvas vs. Shell should make no difference, as Shells are Canvases.

Grant,

I modified the sample examples you sent with ...

e.gc.drawPolyline(points);

and it draws the polyline.  Looks like fillPolygon fails to draw.
Same behavior on the canvas too. But, it does not hang as it use
to, running the "controlexample" or the "eclipse" itself using the
fillPolygon, shell popsup without fillPolygon.
