each rotation of the molecule in chimera will unexpectedly add an extra "c" at command line

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. [image: image.png] [image: image.png] [image: image.png] 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

It is unlikely that Chimera is doing this. Please try using a different keyboard with your computer to check if that is the issue. Or, perhaps you have a programmable mouse, and it's the software that supports that. If you fix your problem, please let us know how you did it. If you can't fix your problem, please use Chimera's Help / Report a Bug dialog to report it. -- Greg On 3/3/2021 12:59 PM, xiaoyu liu wrote:
