Hello,
I have this strange situation in the DrGeo window where scroll events
are not always caught by the underneath canvas.
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?
Hilaire
