I have an AIR application and whenever I uncheck "Generate accessible SWF" then go back to look at the options, the field "Generate accessible SWF" is still checked. My process is
1.Uncheck "Generate accessible SWF"
4.Close Compiler Options Window.
5.Reopen Compiler Options Window
6.Observe a check indicator menacingly starring back at you from "Generate Accessible SWF file"
I have also tried using the compiler option with no luck -accessible=false.
The problem was that my project requires IBM ILog Elixir files. I hadn't installed those files yet, so
for some reason the -accessible=false option was being ignored. After adding the Elixir files the application ran normally.
