Hi Walter, this is an old post but just wondered if you knew whether it’s possible to set the layer for the trackMatte in the latest version of after effects. Previous versions always used the layer above, but you can now choose. Appreciate your advice, thanks in advance! 😃

Hi Reuben, happy new year! i’m experiencing exactly the same problem, did you have any luck using the suppressDialogs? I’ve tried this within the function called by the mouseover event listener, but it’s still causing the scriptUI to freeze. Be great to hear from you, thanks!
