[news.eclipse.tools] Hover event will not work.

["Randy Hudson" <none@xxxxxxx>]

The Hover event will not work for us because you only get the event once.
You have to exit the Canvas in order to get another event.  We need a way to
"reset" the hover when a certain region within a Control has been exited,
but the mouse is still over the control.  Is there any way to do this?
