I am leaving for a resort tomorrow :), which means that I don't have time to play around with the new version till Wednesday :(
Just FYI, Nums on how to get that graphs bug: start a new sim with mutations disabled. This will make sure that "Average mutations" graph is completely empty. Open "Average mutations" graph and then close it - it will casue error 6 (overflow) and crash the program.
As I mentioned before, the problem appears only when there is absolutely no information present on the graph (as in case described above), but it is bothersome to me: I often open and close several graphs in the very beginning of a sim, so that I can come back later and check on what was going on.
