Hi Damien, Another option that the Chimera folks put together is the ability to "focus" using the mouse. If you go to the mouse preferences, you'll see the combination to use your mouse to "center". I've adjusted my settings to use the right mouse button to center. I think this along with Elaine's response will help a lot.

Hi Damien, I don't know anything specific about this, but based on the message, you could try using menu: Actions… Focus (or command "focus") to see if that allows you to zoom further.

I cannot be closer than in the image below, the zooming function is at its maximum. When zooming, I get the error message : refocus to continue scaling I do not know whether it is a bug or something I'm doing wrong.
