[PyMOL] double-click

[Nat Echols]

This is a new pet peeve of mine: it's too easy to select a residue instead 
of bringing up the menu of actions.  I still haven't figured out what the 
difference is, but I keep selecting by mistake.  Is there any way to 
either control the sensitivity of the clicking, or turn off mouse 
selections altogether?  (I tried changing mouse_selection_mode but this 
didn't help, and now it's stuck selecting everything with a single click.)

thanks,
Nat
