Hi,
It sounds like you are doing things correctly, but in my tests it works fine to change the angle. It cannot change the angle if the two bonds are in the same ring, but in that case, there should be a message on the dialog that says so. The bonds must really be adjacent, but it sounds like you understood that part.
To report a problem, we suggest you use the Chimera menu: Help... Report a Bug. In the resulting dialog you could attach a session file (for example with your structure and the two bonds selected) or other input, and describe all steps needed to reproduce the problem. Also include your email address so we could respond.
Thanks
Elaine
