Undo Doesn't Work?

[Tomasula Studio Profile]

I've been using the software for five minutes and I couldn't get the undo button to work. The Undo button and drop down menu didn't do anything. I was converting a photo to Black and White and wanted to revert to the original. I had to hit Cancel in the Tone Sliders Adjustment window to get my original photo back.

Could be human error. Or could be buggy software.

I'm on a Mac using OS X 10.6.7.

Sometimes you have to press undo a few times to get all the way back to where you want to be. This will be improved in the next release.
