Thanks for replies. I'm using IE. Norton's upgrade was installed a few days ago. I went into
that and turned off all the security stuff, the problem stopped. I then experimented with turning each back on and testing to see if the problem started again. Turned everything back on, site is still working correctly. However, it had seemingly fixed itself before for a short time then resumed, so I am at a loss. Also, the problem didn't start immediately after the upgrade. As I said, this is new for me. And speaking of Norton's, it sure is different from the older versions. It no longer blocks ads, even the especially annoying ones that talk or sing to me! Arghhh! I wonder if there's a financial stake for Norton's in allowing ads?
