So I previously had the Gala preview installed and everything worked flawlessly. I figured the update to the standard Flash would be stable, so I upgraded...big mistake. Now, whenever I attempt to watch anything in full screen in HD (on Youtube), it plays fine, then Safari crashes when the video ends. I've tried various things - repaired/verified permissions, etc.; started the video using dynamic switching and only using the discreet card; I even tried deleting the plug-in and re-installing Gala, but I get an installation failure message. Any ideas? Anyone else having problems?
