New to Flex and I was wondering how to ensure my Flex apps will run properly on Flash Player 9? Our organization has some Win 98 PC's in our call center and based on system requirements it looks like FP9 should be my target platform until some upgrades are completed.
By default Flex apps target the FP 9.0.124, you can always check on: Project properties - Flex Compiler - Requiere Flash Player Version
So in Flex Builder if I use some code that requires FP10 it will display a message or error during compile if I have my project set to require FP9?
Yes because those libraries won't be available.
