friction forces

[alex25]

something really strange is happening with the friction forces (i think). if i drive through a sand trap the engine stays unresponsive even when i get back to a normal surface (i would expect the car to start accelerating once i am out of the gravel). if i stop the car and then try to accelerate then the car behaves normally again. i saved a session that illustrates this, you can get it from http://caliban.lbl.gov/vdrift/frictionbug.vdr

also the url tag doesn't seem to work in messages any more.
