After waiting for a few minutes and seeing the loading icon wasn't moving, I used the Power button to shut it off unfortunately I noticed the icon moving again just as I did this. The computer took a long time to log in again, and it seemed like it had frozen. I figured I would have to re-install Opera again, since this fixed the same sort of problem last time, but I tried restarting my computer just in case. When it started up again, Opera was having the same issue as the last time this happened the top and bottom of the screen had changed and I couldn't access the Minimize/RestoreDown/Close buttons. I'm not sure what I did, but it's happened once before the video took up the entire screen, was difficult to manage because I couldn't bring it back to the usual size, and I had to close down the browser itself. Late in the evening, however, my Opera browser had some kind of problem while I was on Youtube. I didn't think much of it because it worked fine for most of the day besides being slow now and then when opening a program or two (The main one I recall is having trouble opening Libre Office). Yesterday morning, my computer took unusually long to log in. I've been told to be as detailed as I can, so I'll try and put my experience and problems down as comprehensively as possible. Hello this is my first time using these forums.
