The drgeo windows is composed with several submorphs: wheels and a sort of PasteUpMorph as the canvas. In this canvas I can handle events as mouse down, hover, over and scroll. They are handled just fine. However when the mouse cursor moves away from the window then comes back, the scroll events are not caught anymore by the canvas. Somehow if I click on the window title, scroll event handling may come back, or not, it is a bit random. The issue seems to be related to mouse focus, not sure. Any idea?
