An annoying frame with interrupted lines periodically appears around my photo and goes away when I go to View/Extra and click on it. I can't figure out what causes it to happen---does anybody know? Also, I would like to permanently disable it. Anybody know how to do that? Thanks. Photoshop CS6, Mac OS OS 10.7.3
Maybe your seeing the transform controls that show when you select the Move Tool?
Does the "frame" go away when you press Ctrl + H or Ctrl +D ? If so, you are somehow activating the Select All feature, which puts a selection (the dashed-line path) around your image. Normally that is activated with the shortcut of Ctrl + A. Have you redefined the shortcut for Select All ?
Do you have the crop tool selected? It always puts up a crop frame around the image. In a quick test here the crop frame will temporarily disappear when I click uncheck View > Extra. Looks like uncheck view > Extra also performs the function of 'hide' Control-H. Try changing to a different tool and see if frame goes away.
