Hi, thanks for your help.

VMD prints the following message ..

My system has more than 100K atoms, and I was able to view the trajectory
on my old computer (maybe it has better graphics chip from NVIDIA).

I really hope the new Intel i series CPUs have an OK graphics integrated.
Could you advice me how to check and fix what might be misconfigured?
Thanks a lot!
