Proximity sensor problem

Is anyone else having a problem with the proximity sensor on their Imagio? After a call connects, and I put the phone to my ear, the screen will go off. Cool.

However, it ALWAYS comes back on at some point in long calls, and I invariably activate some other function of the phone by accident with my chin. After the first few times this happened I became super careful about not moving the unit around too much, but it still happens with regularity.

Anyone else having this problem? I'll admit this is my first touchscreen device, so maybe there's something I'm missing?

Thanks.
