A very odd behaviour! If I pull up the BBC website in FF and move to any news item or article, then my vertical scrollbar is disabled. I can re-enable it by reloading the page and the problem does not recur for the rest of the session. (Just very occasionally it happens after the second navigation rather than the first). Trivial I know, but an irritation (as well as a malfunction!)

I also have the taskbar fails to display in FF, curable by a double-tap on the Win Key. Is this going to be sorted on an update? Also trivial/irritation! TIA
