Hi Bill is that not called X2 or what ever it was called before the Live Effects Tool? It is a good idea to clean out the bits that some of us don't think are as quite important to us in everyday drawing. I was finding that the speed was not quite there when I upgraded to Pro 5, then I had a thought (a dangerous event), I stopped putting the path in on all the Plugin folders that I had, suddenly I had my speed back again.
