Adobe has always been unreliable in Google Chrome. It must have broken something in a recent update (Chrome or Adobe). I can't give any advice ... just hoping the problem doesn't hit my computer at home.
I think it was you who posted on something like this a few months ago. At the time I gave you steps to disable Chrome's version of flash called pepper flash.
You might want to check on that again because it sometimes gets refreshed when Google does a chrome update.
Frank why do you not just go back to a restore point before the problem had shown up?
