as for my part I do not like the popups drifting up from the bottom of the screen very much, it seems like a flurry to me.
In our case some of the popups need some time to build up (you know the ActiveX controls) and so the popup glues to the bottom while initializing and then suddenly jumps to the middle of the screen.
Could you make this feature configurable?
yes, it was not only you who told us that the "flying popup" was not toooo nice for "bigger popups"... We took it back as consequence - and exchanged the animation effect by a dimming.
