Hi Everyone,


   I am using VMD 1.8.6 and trying to color a molecular surface by mapping
electrostatics results from an APBS calculation. I am using the dataset
from the colorbypot VMD tutorial to make sure I understand how to do this.
When I select Color Method as Volume and Drawing Method as Surf VMD produces
a "dotted" representation of the molecular surface. It does not produce the
nice smooth Opaque surface I get when I change Color Method to Charge. The
graphics card is an Intel 945GM. Has anyone run into this problem and if so
is their a work around?


   Best Regards,
