[PyMOL] disappearing data

[David B. <bo...@re...>]

Often, when zooming in and out, the molecule I am looking at will 
disappear.  Looks like this happens mostly upon zooming out (or scaling 
the object down--not sure exactly how this is implemented) when the 
frame rate is relatively low (large molecule/rendering 
surfaces/stereo/etc.).  I can type "zoom all," which will fix things, 
however it can be quite annoying to have to do this often, and it seems 
like this should be a relatively easy fix.  Any thoughts?  Thanks,

David
