[PyMOL] weird behavior with renitialize

[Mooers, B. H.M. (HSC) <Bla...@ou...>]

Dear PyMOLers,

I am using incentive version 1.8.0.5.  I made the following python script with an alias

from pymol import *
cmd.alias('q1', 'delete all;fetch 3v6d, HIVrt, type=pdb, async=0;preset.ball_and_stick("c. P and i. 822");zoom c. P and i. 822;rock')

Repeated entry of the alias name changes the color scheme of the atoms and toggles on and off the rocking motion.
Apparently, the settings are not reset with "delete all".

If I replace "delete all" with "remove all" or 'reinitialize", the command history windows shows the pdb file haveing been fetched but no molecular object show ups in the internal gui. In version 1.55, reinitialize works as expected.

It seems that the reinitialize needs a "pause until completed signal" like "async=0 " in fetch or the unix "&&".

Best regards,

Blaine
