After yesterday when 'stop script' did nothing, 'continue' did nothing and shutting down/reopening the browser also did nothing, it seems fine today! No idea what started it or indeed why it sorted itself. How's yours?
I’ve had the message now and again in the past but not very often now. However as Sheila says, I just click on the button to stop script or even the other one to continue and then it works. I’ve always attributed it to adverts on my Yahoo.com mail page.
Get this several times a week. Switched to Google Chrome and it didn't happen so often but found Chrome a bit slow, so went back to Firefox. I just click on "Stop Script". I think it's a Flash problem.
