I was closing tabs on a window when everything froze. I had about 6 windows open and now they show nothing but white and cannot be interacted with besides closing through task manager. So far I've tried: restarting my pc, re-installing with and without deleting user data, complete deletion and fresh installation.

I have 6 windows of Opera open, and after a restart, I can open all of them except for one. When I attempt to open the 6th tab (where I have everything worthwhile), it will not come to the foreground or allow me to manipulate it beyond the options presented when hovering over the taskbar window. Audio from the window will still play and is currently driving me nuts. Is there anyway to get this window back to normal? Closing it isn't an option if I can't recover it, but I'm worried I won't be able to get to it anyway.
