Menu items are not persistent between Jmol sessions...
Preferences are.

Often, i.e. I often switch on/off hydrogen, charges, labels...
I less often switch on/off antialiasing, etc...
Note that User X turns on shading when exporting images, but
does his rotation work/analysis without shading...

I am not sure how Jmol was behaving in the past... but I imagine this design
handy:

1. the preferences are the boot settings... i.e. the values the several 
rendering options when Jmol is started...
2. we should define a list of options that the users is likely to change
within one Jmol session. These should have menu items, the others not...
The option values toggled with the menu do not alter the preference settings, 
which only indicate the startup values

Not sure if I make myself perfectly clear... but anyway, here is a second try:

1. For labeling, shading, etc, both menu and preferences exist...
    The preferences define the boot settings and the initial menu settings...
    In the Jmol session itself the menu settings do not change the boot 
    setting, but change only the current working settings... Changing the
    preferences changes the boot settings and the current working settings.
2. antialiasing, etc only occur in the preference dialog and determine both
    the boot settings and the current working settings...

Did this help?
