I don't even have this setting option and when playing several games my pages all have to be reloaded every time
I switch off of them, A lot of the time opera just sits there real dumb until I click on refresh which loses my progress if I'm in the middle of a game.. Clicking on disable button does nothing for that tab either. Just my opinion this a badly implemented unwanted feature. let me know when this feature is controllable and I sure don't think I will like this feature either -(New] Hot Tabs Killer – slash tabs that use too much RAM or CPU. Killing my tabs because of memory really should be a non issue at this point in our tech.
