I thought it was "reset", but I see now it is the "rotate x 90" which is cancelling the spin.
You should be ok using the conditional that I proposed, that checks spinning state BEFORE doing anything and later restores it. And being so, I think it can be shortened to this alternative: Jmol.jmolCheckbox(myJmol, "reset;", "reset; if (_spinning);rotate x 90;spin on;else;rotate x 90;endif;", " Toggle Base-stacking view"); ------------------------------------------------------------------------------ _______________________________________________ Jmol-users mailing list [email protected] https://lists.sourceforge.net/lists/listinfo/jmol-users
