Comment 2 for bug 1372151

Ooohh, I didn't realize the icons were missing. I thought they had been changed.

Now, the Redo button does seem to work. But there is some kind of issue. When I first open a new blank file, and draw some quick lines and shapes, and do one or more undos, it doesn't work. And then it does. I don't know what happened to make it start working.

What I mean is that the button is grayed out, even if I have made a few Undo actions. And nothing happens when clicking on it. Same for Edit menu > Redo, and same with whatever the key shortcut is.

Let me see if I can isolate better, what causes it to start working. I'll post again soon.
