For some reason, after the sequence alignment feature was added to Foldit, global wiggling seems to have slowed down on my computer-- in the sense that sometimes creating an obvious clash with a score drop of several hundreds or even thousands of points would only be wiggled out slowly (e.g. point by point). However, reloading the puzzle and re-calling the wiggle function again would be enough to kick-start the process-- once, that is.

Is this a bug, or does this have something to do with the fact that I have to run Foldit on single core (because running it with both cores would eventually overheat my laptop's CPU)?
