I have been using Blocks for a little over a month and am getting very frustrated with it. Setting up scans are easy, Worden is great for helping create the scans you want, but the physically running the scans is horrible. I do not mind that the scans are slow, but when you run a 18 hour scan, only to have it crash with a hour left, makes me want to scream. Tech support says, buy more ram, I am up to 1.5 gigs. I am at the point that I want to go out and spend a grand or two on a new computer to see if it would work better, but that might not work either.
