I haven't experienced this bug for a month at least, maybe two. Is it fixed?

@l33t4opera Thanks, I'll test them. Optimally I'd like to get rid of the tabs at the top, but maybe one of these will do for now.

I don't have any new info on this, but just wanted to say that I haven't seen this behavious yet in the newest 33.0 build.
Not usre if it's fixed, but I'll report if it happens again.

How come there's no word from developers on this?

Can you give us an update on the situation of vertical tabs? Are they ever coming back?

When do you implement vertical tabs? ffs it's been ages and it was (for me at least) the best feature in old opera.

Answer me this: why do I have to allow for a video to go to fullscreen? And now I also have to tick"remember this setting". _In Chrome you can go to fullscreen excpetions and just put all the websites in there(on my own responsibility) and no more annoying messages. For whatever reason I can't edit those excpetions in opera, even though I can see the list.
Why do I have to see "press esc to..." -message or "You have gone full screen"? EVERYONE KNOWS THEY HAVE GONE FULLSCREEN.
I'm not a toddler, I can figure this shit out.

Please do something about this.

I had had the same browser session open for ages(day or two) and had opened and closed tons of tabs during, I probably cleared browsing data multiple times too out of habit.
Maybe it has something to do with long continous browsing sessions?
I keep my browser open always and pretty much close it only when this bug appears.
I was stupid and didn't check the memory allocations or anything in-depth, but I'll try to remember the next time the bug appears.

@avl I have a bit more info on this. This just happened again. I was on imgur, had been for hours and didn't do anything out of ordinary. I think the bug "activated" as I close the imgur tab, but I'm not 100% certain. I always notice it when I try to close a tab and the down-right mouse gesture only shows the context menu(right click).

The mouse gestures and keystrokes seem to stop working only inside the opera window.
I could still write to the address bar, but not on this comment box for example.
Also all keycommands (like ctrl+w) stop working.

Re-opening the tab does nothing and the problem persists on all tabs, but restarting opera fixes it.

I have the same problem with windows 8.1.

I haven't been able to pin it down, it seems somewhat random. I've encountered the problem in youtube and google search.
Seemingly without anything out of ordinary happening, maybe opening a link and closing it, the mouse gestures and keystrokes stop working.
Keyboard still works elsewhere normally and restarting opera fixes the problem. Sometimes the bug has appeared often in a row and then a day or two with nothing.

I have logitech gaming software 8.50.281 installed for my mouse and keyboard.
