[Chimera-users] display vectors

[Eric Pettersen]

Hi Michał,
	We cannot reproduce the slow playback you’re getting with the per-frame cones.  Our guess is that it’s something else with the trajectory that’s problematic.  Does it have a large nucleic acid in it (with abstracted “Nucleotides” depiction?).  Do you have a molecular surface present (even if hidden [check the Model Panel])?
