Photoshop CS4 - Layer Changing on Step Backward

[Blue Ten]

Hehe, I love Photoshop and CS4 is great, but one thing that always got me was how the layers sometimes change when you Step Backward (if you had been on a different layer one history state prior). Basically, I draw one thing, ctrl+alt+z, and it undoes the action AND switches back to the previous layer... Some of the time, I don't notice and end up drawing all over a layer I had intended to leave alone, and I end up having to undo it all or fix it if I'd gone beyond the history states XD. It really messes with my productivity.

Is there a way to disable this? It's gotta be a feature and not a glitch, since it was present in CS3 as well.

It's just a minor, slightly annoying issue, but any help would be greatly appreciated .

First of all, are you using brushes or are you using shapes to draw?

If you are using the shapes tool, normally that creates a new layer. Undoing that will ofcourse undo that layer as well.

UNLESS... You create a new layer, then do the shapes tool. Then it would only undo the shape tool because that is 1 step backward.

If you created a new layer and then started using the airbrush or any of the brush tools, then I can't really help you because airbrush and brush tools don't create layers while using them. :P

Oops, forgot to mention that XD. Yeah, I'm just using the brush. Basically in a situation like this I have at least two layers already set up -- I'd change to one of them and then make one stroke with the brush, but if I step backward right after that first stroke, it undoes the action and switches back to the previously active layer o_O

I use a tablet and always try to get clean looking lines in one stroke of the brush, so I'm using ctrl+alt+z quite a lot after just one stroke.
