I don't know if this is a bug or if it's normal, but in cs4 (on windows 7 64 bit) if I click on a window/picture that is behind another one, my current tool will apply it's action to the picture I clicked. For example, say I have the brush tool currently selected and I have two or three pictures open (not tabbed). If I want to bring the picture in the back to the top of the stack I have to be careful to only click the picture's blue title bar. If I click somewhere on the picture itself the picture will jump to the top AND have a brush stroke applied. Is there a way to turn this off? I have the earlier cs3 on an xp computer it does not have this issue. Clicking a picture in the back just brings the picture to the front but won't apply any tool actions.
