Not sure how many have encountered this, searched the DUC and it would seem that it's happened in the past. Bring M, ST, or Surround RTAS Waves Dorrough plug onto track and it works fine. Click anywhere inside the UI of the Dorrough plug - not just the buttons, or size change, truly anywhere - and PT up and quits immediately. I tried it while playing back audio and PT quit, audio futzed out and it was done. PT7.3.1, OS10.4.11, 3GHz Octo Same thing has happened on PT 8.0, OS10.5, Quad Frustrating to say the least. Anyone encounter this? Plug works just fine in Nuendo, etc.
