Thank you for trying out the Chimera 1.7 release candidate. It is extremely useful for us to have it tested a wide variety of computer systems since it works for us locally. Chimera 1.7 uses a different internal mechanism to pick atoms, but it should work on more systems, not less. Please use Chimera's Help / Report a Bug dialog to report this bug and it will tell us a little about your computer that might help me recreate the conditions that cause the bug. -- Greg On 01/21/2013 01:07 AM, francesco oteri wrote:

Dear Chimera's users, I downloaded and installed version 1.7 build 38047 and I noticed that is no longer possible to select atoms through mouse. Previously, I used the 1.6 and it was still possible using mouse for selecting atoms. I am wondering whether this function has been removed or I miss something?
