Thanks Crossbow7 and anskyber. Tried both your suggestions but no joy. However, I too see the site at the bottom of the screen ( I had not noticed this before) when it used to appear by the hovered mouse - thanks very much for that Pamy.
Well, thats strange. When I came online a few minutes ago I had 3 downloads to be installed, but before they installed my computer froze and I had to use ctrl, alt, del to shutdown.before shutting down it asked "install updates then shut down" ,I OK it. on rebooting and coming onto PCA I now find that I get a yellow box with the URL site in it as LimestoneRock described when I hover mouse over Click Here and belownext to Explorer logo
