hi performer friends!

in my applications the transparency bin doesnt seem to work properly.
i did an initial
setBinSort(PFSORT_TRANSP_BIN,PFSORT_BACK_TO_FRONT,NULL)
on the channel.
and i was careful not to use overlapping primitives, but still some objects
behind e.g. a transparent window texture are not drawn sometimes, because the
window is drawn first and sets the z-buffer.

how in detail is sorting performed?
by the balance point of the primitives?
or is the sorting not even performed on primitive level?

please help,
   floh
