Subject: [chimerax-users] volume zone - unexpected behavior when newMap false

Hello,

I've been playing with volume zone and having good fun, but...

I've noticed that if I set newMap to false, then the invert option is
ignored (behavior is as though invert is false, even when I specify
invert true).

When newMap is set to true, or not set at all, the invert option has the
effect I expected from reading the documentation.

Am I missing something? Hopefully description above is unambiguous but
let me know if you need step-by-step.

Cheers,
Alexis
