I have a problem with my Acer Crystal Eye webcam from my Acer Aspire 57735Z laptop. I'm using the webcam on MSN or Skye, but when I'm invited by someone to show the webcam, it works OK at the beginning, but after a while its colors are changing. This happens sometimes on Acer Crystal Eye webcam itself. I can't change the color and the zoom. Also, I can't find the video control. What can I do?
