[Chimera-users] distance measurement

[Elaine Meng]

Hello Farhana,
I just tried version 1.4 and a recent (12/28) daily build of version  
1.5, both Mac Aqua, and did not have this problem.

When you have a problem, it is better to use "Help... Report a Bug" in  
the Chimera menu (instead of sending e-mail here) because the report  
automatically includes important information such as what version of  
Chimera you are using and what kind of computer. There will an area to  
type a description of the problem and to include your e-mail address  
if you are hoping for a reply.

Sorry, we cannot offer advice unless we can reproduce the problem.  I  
can only mention there are other ways to add the distance without  
double-clicking.  For example, you can select the two atoms (Ctrl- 
click, Shift-Ctrl-click) and then use the command "distance sel" or  
the "Create" button on the Distances tool (under Tools... Structure  
Analysis) to add a distance monitor between the two selected atoms.

At least on a Mac, you can also move molecules with the "finger mouse"  
by combining that with various keys, but it is not as easy as using  
the "real mouse."

I hope this helps,
