addForce to cylinder

[sja]

Hello, all.

I've got a cylinder and i addForce to it. My cylinder jumping on Z onley. But if i don't addForce in long time (5-10 seconds), then if i addForce again then my object is not respond.
what is it ?

I'm having the same problem, but my cylinder is constrained in the up/down (Y) direction, and it seems to happen after a bit moving it up & down. Its constrained to an object that only moves up/down. Its supposed to stay level with it by applying force in a direction, that way it bobs up & down to catch up whenever its parent object moves. It works fine at first, but then for some reason, at some point it stops moving, like its constraint changed positions or something.
