I'm having all kinds of browser problems -- it's a long saga. I was just hoping that it might be something that could be fixed at source. I can't view most graphics on BlueSky, but some come through. Don't know why.

Don't worry about it. I'm trying to get a good Linux setup and then make that my "usual" workstation. It's taking time, for a variety of excrutiatingly tedious reasons (mostly having to do with not spending any more money).
