Just a report. I was trying out the new cooking iso (28 Feb) yesterday and found that Flash 10 is not working. You may not have noticed this at that time.
I realized that Curl was updated to 7.19.4 sometime this week. This upgrade seems to break Flash 10. I downgraded curl to 7.19.2 and flash 10 works again. It may be an issue of indirect dependency with 7.19.4. Will try to find this out and report back soon.
