Just like what Snappyd mentioned about windows, i've experienced it too. Before windows update, there's no problem occured at all. But after the update, chrome's shockwave flash starts to crash every 5 minutes i use flash related sites.
I've also tried the procedure that ladams1221 suggests and even uninstalled and installed back the Chrome. Sadly, it didn't work..
Maybe because window's update and chrome's update are not parallel.
Chrome might need time to keep up with windows. I think so...
