Adobe Flash Broken For Obvious Case?

[Ma Xiaojun]

Hi,

( I know this can be made into a bug report. )

On 13.04 64bit with Adobe Flash installed.

Go to youtube.com, play any video, right-click and select "Settings..."
Then a dialog pops up, but it doesn't respond to user click at all;
the only way to "close" it is refresh the page...

I know Adobe may be the one to blame. But can we workaround in our side?

If this issue is hardware dependent, I'm running Ubuntu on an MacBook
Pro (8.1 something) with Intel graphics.
