Thanks Mike. I gave that a go, and indeed the spinning circle was there. I still can't get it showing on FF however, though I'm surprised to see it spinning in the Bing box on IE.
I don't know if it was there before trying mouse thingies.
It has always been at the top right as of first load of OS.
The second Goog-le box goes right to the end now that I've removed the secondary Skype button/logo. I don't need that there and wonder if it is inhibiting the circle from appearing, but can't get rid of it. I can move the dividing point along, but it insists on staying glued to the right edge.
Is there anything that commands the position of the spinning circle on the screen?
