OK, I went to Ninite to see what Opera there is and now that it's installed tell me how to duplicate the issue.
I have Windows10 on two ASUS Systems, and both are having problems with Opera. what happens is i go to a URL and start browsing and all at once i start getting these black box's on screen, then the screen go's all black. If i close Opera i can open it again and the same thing will still happen. Have tried removing the Opera program, and reinstalling it no change. Google Chrome has no problem like this but Chrome does not display at top of the browser like Opera.
It seems to have started after the last few Win10 upgrades.
