Physical Zone delayed?

Ok, I'm creating some more fun in Zap, so I thought I'd put some jump ramps in.

So, I take a physical zone, and shove it at the end of a ramp. The zone basicaly has a gravity mod of -100, velocity mod of 1 (no change) and applied force of 0,0,0

But when I run over the physical zone, it doesnt apply the force straight away as I'd expect, it actually seems to kick in after a second or so.

So you get a jump, fall, oohh high in the air motion :))

Not quite what I'd expected. I want the player to be impulse'd up in the air as soon as he hits the zone.

I guess to do it right, I'd also want to get the collision normal to the plane the player hits to use as the impulse vector, but thats another story.

Anyone know why the lag?

Phil.
