Hi Steffen,

Was this the very first time you had ever used ChimeraX, or did you mean the error happened as you started ChimeraX without you doing anything else? Does this error happen every time you start ChimeraX, or was it only this one time?

Hi Eric,

It was the first time facing this problem. It happened on the first 
start of the programm after installing (I use the programm for some time 
now, but installed it on a new laptop). Maybe the programm did start in 
the background after the installation process and I was too impatient 
with starting the programm. I have started it several times since then 
without any issues.

Hi Steffen,

Thanks for getting back to me. This feels like a problem that I'm never going to be able to reproduce, and since it doesn't recur for you either, I am just going to close this ticket. Keep your fingers crossed. :-)

Hi Steffen,

I did get another report of this, so I made my best guess as to what would fix it and changed the code. Thanks for reporting the problem so I could get a feel for whether it was common or not.

Thanks for letting me know. And thanks for your work, I really like the 
new chimeraX ;)

Best regards,
