That really depends on your system, and unfortunately, we haven't found a commonality to say "yes" or "no" for any given computer. Some people have had little to no problems with p5 and others have lots of issues. Personally, I'm considering getting a third party library management program and going back to P4. (I have a ton of folder files.) Others will tell you that P5 rocks. And, no, they're not lying. It's the luck of the draw. Prepare for a lot of responses, good and bad, about P5.
