Sorry to hear, but I've had the same issue for a month or more and tried everything.....no help here...I disabled all add-ons to see if there was a conflict, but as soon as I ran Flash on its own with only the shockwave add-on it crashed or in Google terms became un-responsive.. I've updated drivers have all the latest security patches etc, unchecked accelerators. I hope you get it sorted out, but dont hold your breath, and please realise that all help here is from other users NOT from Adobe....they only care if you have $39 to call the help line....Nice business....put out faulty software and charge to fix it....now why didnt I think of that?....great business model until people catch on!
You don't give us your operating system, so I can only make a few vague suggestions...
- update the drivers for your graphics/video/display adapter;
- disable Hardware Acceleration (Flash Player Settings);
- try changing some settings at http://www.macromedia.com/support/documentation/en/flashplayer/help/settings_manager.html - e.g. allow 3rd-party content, delete stored Flash data, etc.
- try starting your browser(s) in Safe Mode (browser Safe Mode, not Windows Safe Mode).
