Our team's PYTHONPATH variable has a hyphen in the name. It's causing some of our artitst to be unable to launch Painter. According to your documentation, hyphens are considered illegal characters.
This seems a little heavy handed. Any chance this can get fixed in a future version?
After some additional investigation, I think this might be a red herring. I'll follow-up when I can determine the cause of the crash with some certainty.
