[PyMOL] Do presets lock settings?

[Olivier Julien]

Hi,

I am using pymol v0.99-rc6 on a linux machine. I really like the preset 
feature (publication, pretty etc.) It's fast and easy when you want to 
compare structures.

However, it seems that when I am using this tool at first, I can't 
modified the settings after that. For example, if I am using the 
publication preset, I can not change the loops setting to "smooth loops" 
anymore. The settings are all locked. Is there a way to avoid this 
problem???

Thanks,

Olivier
