I'm seeing issues undoing on OS X... wondering if anyone else is seeing this.
Sometimes when I undo, it works as expected. Other times, if I monkey-mash Command-Z, it eventually undoes the last thing I did.
In fact, it seems to stop working properly after the first undo.
Steps to reproduce:
1) Open Spine.
2) Rotate an image.
3) Command-Z to undo. (Should work).
4) Rotate image again.
5) Command-Z to undo. (Fails for me).
6) Monkey-mash Command-Z for a while. (Eventually undoes the rotate).
It seems like if you let go of the command key, and then re-press it between attempts it's more likely to succeed. If you hold command the entire time and just press "z" while it's in the failed state it doesn't seem to ever recover.
If you let go of command and re-press it in between attempts it doesn't always work immediately... sometimes it still fails, but other times it seems fine.
Happens in Java 6 and Java 7.
