I can Create Video FX Sources and Viewers in ISBoxer no problem:
I can also Hide and Show Viewers OK.
However I cannot get the Video FX Destroy Action to work:
I want to use the Destroy action within ISBoxer, as it appears that you cannot create a new viewer that overlaps the area used by a previous viewer, even when the previous viewer has been hidden.
Therefore it appears to me that the only way to implement different viewers that use the same screen space and are swapped between via a hotkey is to destroy the previous viewer and then create the new one each time they're swapped(?)
Thanks for any advice or insights!
