[Chimera-users] each rotation of the molecule in chimera will unexpectedly add an extra "c" at command line

[xiaoyu liu]

Hello,

I'm Xiaoyu Liu, a chimera user. Thank you for developing and sharing this
powerful software. I have a problem now and bothered me for a while when
using chimera. I'm wondering if you know how to solve it.

I downloaded chimera-1.15-mac64.dmg
<https://www.cgl.ucsf.edu/chimera/cgi-bin/secure/chimera-get.py?file=mac64/chimera-1.15-mac64.dmg>
 from "https://www.cgl.ucsf.edu/chimera/download.html" for  my Mac OS
Catalina(10.15.5). When I rotate the molecule with left mouse button, an
extra character "c" will be automatically added in command line. Each
rotation will result in adding one "c". Here I have some screen shot to
show more clearly.

I tried to restart my computer. It is helpful within the first 10 minutes
after the restart, but later it has the problem again. Please let me know
if you know how to solve it. Many thanks!

Best,
Xiaoyu
