Thank you for all your responses. It's still doing it, but not when I access other sites. I don't believe it's a virus, because our computer is well-protected, and it's only Mudcat that's affected. It's totally maddening, as I love Mudcat and enjoy reading everything here and posting. We do have problems with a very feeble Broadband signal, only 0.5 megathingies, but this is different, the screen freezes and never moves, even if you leave it for 30mins. If it's connected to the Mudcat page, I wonder if something could be done from your end? Sorry to whinge, but I'm totally ignorant techno-wise!
