I wonder if maybe some of the Flash folders on your computer contain corrupted data.
There are two Macromedia Flash Player folders on my Win7 computer whose contents I delete every day, sometimes even several times a day. One is "QPQ9G3J9" and the other is the "sys" folder.
Maybe clearing these out on your computer would help with your situation.
These folders contain trash like user settings and timers that are placed there every time you visit a website that uses Flash. The files are mainly there to recognize your computer when you visit a site again or for tracking and timer counters for usage monitoring with things like Pandora.
They are located at:
(C:/)Users/"YourUserName"/AppData/Roaming/Macromedia/FlashPlayer/#SharedObjects/QPQ9G3J9
(C:/)Users/"YourUserName"/AppData/Roaming/Macromedia/FlashPlayer/macromedia.com/support/flashplayer/sys
