The subject line summarizes the challenge. I can open all other file types of interest (pdb, pyc, py) for viewing. However, I am unable to open a pdbqt vinaout file within Chimera 1.13.

The result: Chimera session freezes and can only be shut down through the Windows 10 task manager. Have uninstall and reinstalled Chimera, cycled computer off and back on, and updated graphic driver and rolled by graphic driver to previous version, all to no avail.

Windows 10 64-bit

Chimera 1.13

Graphics Card: AMD Radeon 480

Memory: 11 GB
