This issue (flying toasts) will be fixed before July 31st, via an update. I
suspect that will also take care of the multiple copies, which I think in
this case relate to unanswered alerts.
(sorry--mine's bog standard horizontal on the bottom three rows high!) But
I do understand the issue--I've watched it in action--it happens with any
vertical taskbar but not with any horizontal taskbar, so we can't claim that
it is politically sensitive, but....(nah..better not go there.)
At any rate--I'm unclear what the behavior is with an other than vertical or
horizontal taskbar, but I'm sure somebody could post a photoshopped
suggestion!
