I just got my 3rd Treo600 today, and the 'down' button in the 5-way navigator seems harder to activate than the rest, need to push it really hard for it to work. Anyone experienced this ?

My first replacement (2nd set), had a sticky 'left' and 'right' button, and I lived with it, but after a while the buttons near the sides (Q, A, option, Z, P, O, L, etc) all couldn't work so I had to send it in, and now this.

Is this sticky navigator a problem, or should I just live with it for now. By the way, this set took 14 days to arrive, so I really can't bear to send it in again.
