I've been using VMD1.9beta3 my box (Ubuntu 10.04, AMD64-bit, with Nvidia
GTX 275 graphics, NVIDIA driver 260.19.36) successfully for a month
now. I thought I would do myself the favor of springing for a second
monitor. The dual screen layout set up smoothly in the NVIDIA S Server
Settings software, and works as expected for most routine purposes.

But when I now try to start VMD I get an "invalid window parameter
error", specifically:

This isn't a specific VMD problem; I get analogous errors also with
PyMol and Chimera. But I can glean no help from the web at large, so
thought I would see if other VMDers had had a similar problem. I'm
totally at a loss, and would appreciate any hints.
