[Chimera-users] lost focus wile rotating molecules after zoom-in

Your case #1 is normal Chimera 1.4 behavior as described in the
"center of rotation method:
front center (default) - when the view is zoomed out, behaves like
center of models; when the view is zoomed in on parts of items, behaves
like center of view, except the center of rotation depth (Z-coordinate)
is set to that of the frontmost displayed unclipped atom whose VDW
sphere intercepts a line perpendicular to the screen in the window
center. The center is not updated when only rotations are performed. "
If you prefer the Chimera 1.3 behavior where rotation is about the
center of the molecule even when you are zoomed in then set the rotation
center to "center of models" and save that setting for future sessions.
Details are on the above web page.
For case #2 that is a bug with the Model Panel dialog Focus button in
Chimera 1.4 and I'll look at it shortly.

> Dear Greg,

> I'm using ver. 1.4 (build 29251) Chimera running on CentOS 5.x x86_64 Linux. I make a description here first and then I will try to report it through Help dialog. The term "lost focus" I have mentioned means that the centroid of molecule do not always be kept at the center of window.
> Condition #1. Open a protein structure, and then click FOCUS from ACTIONS of the main menu without selecting anything. After doing zoom-in, rotation, and then zoom-out, the position of molecular centroid migrated.
> Condition #2. Open a protein and it's ligand in the same session followed by opening MODEL PANEL dialog. Selecting ligand and then focusing it from MODEL PANEL dialog, you will find Chimera do not focus the ligand once molecules are rotated. However, it works fine while selection and focusing are done through main menu.
