Thank you guys!!! The suggestion about Cntrl+alt+Q worked (btw, alt and option are the same key on a mac). Oddly enough, I now have on minimal things...just a dress and shoes. My friend took a screenshot of me a few days ago before I could see myself and I had on all sorts of things (glasses, wristbands, legwarmers, gigantic shopping bag...). Does this command kind of strip things down? I'm not complaining...the getup my professor gave me was a bit over the top.
And for the suggestion about downloading another viewer...sounds like it would work, but my professor has us doing all sorts of things and I'd like to stay in the same program as the rest of the class.
I cannot thank you all enough for your help!! What a great community
