Opera has, quite suddenly, ceased to work for me. All I get is two tabs with black screens. If I try to refresh a page, it flshes white, briefly, but then remains black. I suspect it may be something to do with Javascript, but when I try to check Opera's settings, I get a new tab saying loading, but nothing else happens (same black screen).

I've tried completely uninstalling Opera, and then re-installing version 19.0.1326.63 - but this made no difference at all. Could it be something to do with my firewall or antivirus, too (no messages showing that seem to relate to Opera)?

Regards,

Mike.
