Hi all! :-)
Here's a bug that still spawns endless morphic debuggers despite the patch from below:
Rotate a menu item and hover it. Your image will stop working!
[cid:decc3db2-3dce-4bf4-863e-bac20e27c36b]
(I actually fixed this bug in my image, but it requires so many redirections of #owner that I'm not sure whether this is good for Trunk.)
However, the problem is that in #processEventsSafely:, ActiveEvent does not contain the mouseOver event but still a past mouseUp event (which is not high frequent). This leads me to the following question:
Why is #becomeActiveDuring: only sent from #sendEvent:focus:clear: but not from HandMorph >> #handleEvent: directly? If mouseEnter/mouseLeave events are sent via #processMouseOver:, ActiveEvent is not updated. This feels strange to me ... Is this actually a desired behavior? :-)
Best,
Christoph

Slightly refines previous commit. Depends indeed on Morphic-ct.1636.
(Sorry for all the noise! We could really need some kind of branch concept ...)
