Creative-nx pro webcam-poor picture?

Hello,i recently bought a creative webcam NX Pro and had hoped for
better but i find the image quality poor. Perhaps i should have done
more research but i find that it cannot deal with high light levels
very well and the picture is greatly overexposed. The software has an
auto exposure setting but even if i over-ride this and put it on
manual at the lowest setting,its still overexposed. This only happens
when pointing the cam outside eg looking through a window. Even on
relatively dull days,it cannot cope with high external light levels.

Is this a common thing with webcams or have i perhaps got a faulty
product?

sorry if this is slightly OT for this NG.
