I cant figure this out at all....The Trigger effects section in the editor.... I place a trigger down and when i go to select a Trigger effect ..theres voice and sound effects and music etc listed and i can open the windows and see tons of files listed but I cant select anything and I cant play anything in this section...is all this disabled?? It seems like a great idea but I cant find anyplace that explain how to get this to work.....any help would be appreciated! Thanks
