I am having major editing problems and I have never had this in the three years I have been using EDIUS.

What is happening is when I start a new project everthing is fine. After i start editing a little edits I make start to take a long time before they are scene. Ex. I put a transition on two clips and you see the hour glass for about 5 - 10 seconds before you see the transition on the clip. I have called grass valley and went through all there optimization stuff and even cleared half my Hard drive and still doing the same thing. Has anyone run in to this? And what should i do? I have not done anything to change anything.
