Let's give them credit for their huge achievement in producing such a feature-rich programme in such a short time with so few resources, but be brutally honest that many of us would like it to be faster! There are things that you can do to maximise your chances of a more pleasant experience though: 1 Use the fastest CPU you can find (probably 1.8GHz pentium IV or equivalent is minimum) > on my computer (256MB ram) and uses a large amount of memory 2 More memory will definitely be a big help. Also switch to using pre-computed contours wherever this is sensible. It's pretty easy to switch back to on-the-fly contours when you need them. > becomming more and more slow during the day. 3 save quit & restart when you find this happening. There are memory leaks that are difficult to track down (and are not neccessarily in CCPN code!) that will kill you where your RAM is limiting. > Is this related to the fact I am using Tk as graphics handler?
