Hi, Dear All,<div><br></div><div>I have a mac 10.4 with 4GB memory, I thought it should be pretty fast. However when  I run coot, it&#39;s kind of slow. Even when I push the space key to go to next residue, I can feel it is really walking to the next residue. Is this normal or something maybe not set up correct? I wonder how feasible it is to do modeling in laptop. Sorry for the dumb question, but I just want to get a sense how fast it should be, so that I can have things fixed. THanks.</div>
