I've used Opera for a number of years, currently with W10. Apparently an updated version of Opera was installed a couple of days ago. Now, whenever I open Opera, I have a full screen of the last webpage (presumably) I opened. There are no tabs visible, no url is displayed, no blank url to fill in, no icon on the upper left, no bars to access a drop-down menu...in short, nothing to assist me in going to something other than the webpage which opened unless I go to Task Manager & END TASK and reopen Opera which gives me the same loop. This is tiresome.
I've uninstalled and will reinstall & hope whatever got changed will revert to the original settings.
