Can't use history brush after I extract

I extracted a part of an image and when I try to use the history brush, I get a message that says "Could not use the history brush because the current canvas size does not match that of the history state." I've tried re-sizing the image and then extracting, but that hasn't solved the problem?

How can I get around this?

Thanks for the help!

If anything changes as far as color model, size, resolution, number of layers then the history brush won't work.

Robert is right. You probably did one of those things to effectively disable the use of the history brush. Without seeing your History palette, we couldn't tell you which one caused it. How I get around this problem with the extract command is to do this:

1. Create a duplicate of the layer that you are planning on extracting out. (If this is the background, you might want to create TWO duplicates. There are other ways around it, but that's what I do.)
2. Perform the extract on the layer you want to.
3. Ctrl-Click the extracted layer to select it.
4. Highlight the duplicated layer in the layers palette.
5. Go to "Layer > Add Layer Mask > Reveal Selection" to add a mask to the duplicated layer.
6. Now you can add back in what you are missing from the extract by painting on the mask with any shade of grey you want (Black to hide, white to reveal.)

What a brilliant idea!
Thanks for posting this. I am filing this in my Photoshop Tips folder :)
