Saw the posts, and thought I'd try Flash 10. Didn't have any install problems after removing Flash 9 and using the Adobe Site's .deb pkg for Ubuntu 8.04+. That's scary, because usually Flash has given me a lot of problems installing. With various solutions working at times, as of late 'sudo apt-get install flashplugin-nonfree' was the only way. But, it worked correctly.
I'm using Intrepid Ibex daily build, and there's no issues with it. I noticed where I used to have a framing problem yielding lines at times, this behavior seems to have been corrected.
Seems like a good update.
