With the recent update of firefox, the new security release of flash player plugin 10.0.32.18 was recommended as well. After updating my flash player, all movies i had built within Flash CS3 (in AS3) lost the ability to use LocalConnection. This break in functionality is ONLY apparent on my Mac (LocalConnection still works in Windows). After doing quite a bit of reading about this security release and what it entails, it's apparent that a large portion of it was dedicated to changing the API for LocalConnection in the OS X environment. Their docs state that a new variable of LocalConnection.isPerUser was introduced to the api for backwards compatibility reasons, however since CS3 only compiles to Flash 9, I can't use it.
In short, the security release was not supposed to break older flash movies, and even states that it will still work with AS2 apps. however, any LocalConnection objects published from CS3 to Flash 9 format will not work on my Mac.
I am currently running Snow Leopard (OS X 10.6), flash player plugin 10.0.32.18, CS3 dev environment.
Does anyone have experience with this bug?
