Hi list,

We have a strange problem. We can't seem to start two instances of VMD. I
can start VMD once and get everything to come up. But when I type VMD again
I can't get a second VMD to show up. Here is the output of the first VMD:

Here is what I get when I try to start a second VMD session in debug mode:

Thanks for any hints on this.
