Good idea, I'll have a look.

I just had a look, and indeed, these are very similar - or should be,
in fact, UpdateIfNeeded() doesn't work as it's done now; it would need
to be something more like GetMouse() or even should call DoUpdate()
directly.
But as I think about it: it's a bad idea that there is always only one
_UPDATE_ message in the queue, as it slows down the whole thing quite a
lot; the latency between to (necessary) _UPDATE_ messages is increased
a lot this way and for no reason.
BTW I have tried several apps now under Haiku, and some of them even
run (R5 & Haiku DataTranslation preferences apps, for example, even
though both look kinda strange).
Many of them will let the app_server crash.
How would I try FFM with our app_server? The Mouse preferences app
doesn't work yet (it's one of those that let the app_server crash here)
:-)
Also, why is moving windows so damn slow? I thought it would use
hardware acceleration by now?
Bye,
Axel.
