Continuing from my last posting…
I set view.mousePicker to solve my original problem. However whenever I dispose of that view and create a new view nothing ever gets a mouse event again. Below is the complete source code that illustrates the problem. Move the mouse over the cross in the first ten seconds and see the cursor change. After ten seconds you will see a new view (with different colors) and note that the mouse never gets an event again…. Any ideas?
thanks,
