Ok, so I think the issue is that the Sprite I am drawing in "canvas" is inside
its parent (vis.marks), which has another 100 sprites. Each of the 100 sprites
has a function in library I am using that says on mouseover bring the sprite to
the top of the display list. I think this is overtaking my mouse position thus
the mouse events get lost or hijacked or something.
So I tried taking canvas out of vis.marks layer and making it a child of vis
where marks is located but one level up, so on top of marks.
This still didn't fix the issue. The only to way to fix it is to put all this
on the main stage (aka Application.application). I would prefer not to put this
on the stage unless I have to. Does any one else have any suggestions?
TIA, j
