flash v19 - FSCommand failing due to "security sandbox violation" in windows app

Hello,

I've been dynamically creating the flash player (via COM) in my Windows application to load and play a local SWF file. Some buttons/links communicate with VBScript using FSCommand. It's worked for many years, but the button/link handlers broke with the introduction of Flash Player 19.

In the debug flash 19, I see a bunch of errors like this:

     *** Security Sandbox Violation ***

     FSCommand halted (AllowScriptAccess is 'always'): FSCommand:OnItemSelected

whenever I click a button/link. I made sure allowscriptaccess=always for the object.

Are there any properties or settings I can use to allow the clicks to communicate with VBScript?

Thanks for the help
