Many thanks Everyone, seems I am not alone, which, although not good for everyone, makes me feel a little better..
I have cleared the cache, and it works for a few times, then resorts back. I like the open in new tab option as a quick fix, again, thanks to all.
Another problem I am having with Windows 11 is that on my home screen whenever I close a window, I have to wait up to 30 seconds before hovering the mouse over a shortcut will work. Apparently it is a Windows problem they are not ready to admit yet !!!
