Google’s Chrome browser ships with a different version of Adobe Flash player (10.1.103.19 ) than the current release (10.2.161.23) and is causing various problems for me, most notably the inability to stream my webcam.
Luckily it’s easy to disable. Just visit chrome://plugins and expand to details view. There will be two version of Flash and you can disable the problematic one to fix the problems.
In addition, the version of flash that shipped with OS X 10.6.5 is buggy and may need to be upgraded. I found installing the latest 64bit release alleviated the problems.
