Hi,

I was wondering whether the following should indeed happen, proposing  
that it really shouldn't :-)

I start jmol (latest from SVN:11.1.27) inside the cube directory of  
the jmol-datafiles, so I can load the 2px.cub.gz file several times.  
Initially the memory use is 13 6 64 (MB total free max, respectively,  
from the popup)

Next I do the following load and see what the popup tells me about  
the memory usage:

$ isosurface pos 0.032 "2px.cub.gz"
memory use is : 27 12 64

$ isosurface pos 0.032 "2px.cub.gz"
memory use is : 40 19 64

$ isosurface pos 0.032 "2px.cub.gz"
memory use is: 48 21 64

$ isosurface pos 0.032 "2px.cub.gz"
memory use is : 61 27 64

$ isosurface pos 0.032 "2px.cub.gz"
memory use is : 64 25 64

$ isosurface pos 0.032 "2px.cub.gz"
memory use is : 64 20 64

$ isosurface pos 0.032 "2px.cub.gz"
and Jmol crashes.

I initially encountered the problem with a huge cube file (about 50MB  
big) and noticed that when I had the first surface drawn and written  
the isosurface JVXL file. I could zap the model but the memory was  
not released. I also noticed that as I waited the amount of free  
memory kept diminishing until Jmol crashed. I decided to try to  
reproduce a similar problem with a cube file that is already  
available in the datafiles. Turns out that I didn't even have to  
write a JVXL file to start making this happen.

Thanks,
René
