The latest motm goes round a bit too fast with chime (is this clock-dependent?). Must be close to the epilepsy-inducing rep rate.

I agree that the molecule spins too quickly, and I think I may know why. When Chime reached version 1.0, there was a change in the spinrate parameter, such that "normal" spin rates with older chime versions now spun a lot faster. The parameter is now "degrees per second," with a 30 degree spin of the y axis the default. See http://www.mdli.com/chemscape/chime/chimehelp.html#Dev2 for details. FYI, the current MOTM page is set with SpinY=360, or one rotation per second. When I upgraded to 1.0, I had to slow down all of my overly hyperactive molecules.... (shameless plug: http://www.chem.wisc.edu/~casey/research.html)

No doubt time will allow refinement of the parameters, but would it not be better if using the mouse were to shut down the externally induced spin? Presumably someone going in with a mouse wants to examine still orientations.

Well, it is simple to turn off the rotation using the popup menu, and IMHO it it useful to be able to "tweak" a rotating molecule with the mouse to adjust its spinning orientation. Your mileage may vary, of course... -john nash -==-John R. Nash-==-nash@chem.wisc.edu-==-UW-Madison Chem.
