How do I stop Shockwave Flash from crashing/being unresponsive in chrome 15?

Everything is up to date. And I can replicate the problem 100% of the time by going to a video on youtube or anywhere else that uses flash. Its hard to get around the internet when lots of pages use flash...and then flash crashes -_-  I am using windows 7 on a HP computer. Please pleasepleaseplease help!! Thanks ^_^
