Hi James, There is no chance of us figuring out what happened without much more information. You might try using Help... Report a Bug which would automatically include information about your platform and Chimera version, and also saying in that report exactly what you were doing when the problem occurred, and what happened when it occurred. I.e. was the problem only on displaying objects in Chimera, were any other screen displays (other programs) affected, did it freeze, did you get any error messages, etc. If not and everything is "Shown" according to Model Panel, the only other idea I have is that everything got zoomed or translated out of view. You could try "Actions... Focus" to see if that brings them back into the view. Other than that, it could well be some limitation of your system (memory? graphics capabilities?) since Chimera can be taxing of both, rather than a bug per se. Elaine ----- Elaine C.

I have a sudden problem with the display in version 1.2509. I was working with a session with about 20 models opened. For whatever reason, I just can't display any on the screen anymore; even if all are selected in the model panel. Am I missing something or is this a bug?
