Problem is solved thanks but in answer to your question I did not upgrade Opera. I re-installed it and the problem was there after I did however, after shutdown for the night and re-start in the morning the problem
disappeared which leads me to conclude that I should have shut down and re-started after the fresh install of Opera which I did not do. All that is irrelevant now unless someone else has the same problem then they might be well advised to re-start after upgrade or download. Thanks again.
