I have the Avermedia document camera and I have had some issues with it freezing on me. I will be doing notes or going through an example problem and the screen will freeze. I have to shut down the Aver program and re-open it. Now, some days I can use the camera all day long and no freezing, but then it will freeze every five minutes on other days. Does anybody else experience this? Any ideas on what to do? And no, I'm not just accidently pushing the freeze button!
