[Tom Goddard]

The fault handler output lists 3 "Windows fatal exception: access violation" in 3 different parts of the code, all 3 caused by an expose event and subsequent attempt to draw the status line. The first fatal error is trying to create and initialize the status line OpenGL context supposedly crashing in QOpenGLContext.create(). The second is in calling QOpenGLContext.makeCurrent(). And the third is in glVertexAttribPointer() crashing in PyOpenGL in an import.

How can it get 3 access violations? Why didn't the first one kill the process?

Also mysterious is that the log shows the user opened a PDB, colored it, selected parts of it, and saved an image before all this happened.

I'm baffled. Maybe they were running multiple instances of ChimeraX and the errors came from multiple instances? Maybe the fatal "access violation" errors are not fatal?
