I too, would like to allow Flash to run without being forced to constantly interrupt my work to update Flash! (I update it periodically, but would like to choose the time!!)
It appears that the flag mentioned above in opera://flags has been removed in Opera 32.0.1948.25. Therefore, the option to bypass the 'Update Flash' roadblock appears to be no longer possible! :>(
Has anyone discovered a way to reinstate this option, putting the user back in control of his/her own update schedule??!
