[chimerax-users] measure blob - persistent color?

[Elaine Meng]

Hi Alexis,
Update: yes, it is probably the version.  I happened to have a 6/18 build handy and in that, the color was erased just as you reported.  So if you get the latest daily build, I expect the problem to be solved!
Best,
Elaine
