Hi Rob,
I tried to repro this but am unable to. Here's what I did:
1) Open Max.
2) Create a sphere
3) Create a tyFlow
4) Add Birth Paint to the flow
5) Click the sphere
6) Click "paint" in Birth Paint and draw some particles on the sphere.
The particles appear while drawing and are added to the flow correctly when I release my mouse.
If you reproduce those exact steps do you still get the issue of no particles?
