This evening (2/24/2023) both my computers take forever to bring up the site.
Sometimes I can't even get on.... just shows a blank screen and no loading activity.
If I use the one computer (Win XP) which requires logging in each time, eventually I can bring up the site.
But on this the Win 10 computer, it takes forever. - the "scrolling" bar just keeps repeating.
I've checked my logon saved info, it seems ok.
other sites online are fine and load in a flash.
Any changes made recently?
