Hi Duane,
I would have to ask if that is the correct behavior. I have tested Acroread 4, which has flying toolbars, under both WinNT and wine. And in both cases, the flying toolbar disappears if you don't hold the mouse button down.
Yes, this is the behaviour under all MS Windows versions for our application Signlab, the flying toolbars do NOT disappear.
If Acroread behaves differently it is possible that it is relying on something else to make the flyouts disappear.
