What next?

I cannot get my computer to work right. Could be operator error I suppose. But I keep losing things, and now I can't get photos to post and I cannot get links to post. Just when I think I've got the hang of it, some little green gremlin sneaks into my computer and messes with me. I do have a secret weapon tho. My son is going to be home over Memorial Day and I'm hoping to get him to look at it. He's a computer programer, but unfortunately lives too far away to come every time I need help. When I call him about some of my "problems" he just laughs and says, so what did you do this time?? Or he says, how did you ever do THAT???
