No Undo/Redo function?

[ac3sven]

This must be a stupid question, but I found nothing on the forums.

I have a fresh install of Flash CS4.
The Actionscript Panel has no undo or redo. Am I missing a setting?

Thanks.

On my CS4, the Actionscript panel has multiple undos with CONTROL-Z...

But there are other limitations, which is why, if you're on a PC, get FlashDevelop!
