I have found that removing Flash completely using the Flash uninstaller stopped the hang and crashes. Click for Flash did not help, I still got stalls and crashes.
Besides the 0-Day exploit, there is something going on with Adobe. Maybe they are ****** off that Apple will not port Flash to the iPhone thus deploying buggy Flash Players to Macs.
Flash Player currently is a Big Piece of S#$T. It even spikes my Windose IBM Thinkpad. I hope they fix it but I really do not miss it.
It is interesting to note since Adobe purchased Macromedia, they really screwed everything up. I am concern since most of the new development is by persons of foreign decent, ( India ) are we really getting what we payed for? Are there bugs and malware installed, hence the 0-Day exploit.

I'll just view sites that are non-Flash designed and recommend to all my clients that they do the same until Adobe cleans up their bloated, broken code.
