Same error in this separate instance. Caused by having multiple ChimeraX instances running at the same time, perhaps?

Another case of saving the size of a resized window. It would make sense that this error is _possible_ with multiple ChimeraX instances open, but nonetheless how could you resize multiple instances simultaneously?

[pett]

Could not reproduce this, even when using a "perframe windowsize" command to continuously resize one ChimeraX while manually resizing another.

Am interesting in hearing if it happens again though.
