Sorry Umberto, was away for a couple of days for work. I have flushed the Browser Cache and still no change. It also prompted me to flush the DNS Cache but again no change. I restarted the PC after both actions.
I realise this is a problem with just my PC as I don't see any other posts with the same issue. Is it worth uninstalling and cleaning out the Registry? (I know you don't normally encourage uninstall/reinstall).
To be fair I have had years of no problems but this one has really got me.
