Dear VMD users, I just installed VMD-1.9.2 on the CentOS system. But when I input the command "vmd" in the terminal,  a normal VMD viewer window and a grep MVD main window (without any work or graph) appear, and only a few seconds later, both of these windows disapper. The last few lines in the termial are: Info) Multithreading available, 6 CPUs detected. Info) Free system memory: 22935MB (95%) Info) Creating CUDA device pool and initializing hardware..
