timeslider & numbers dissapeared from NLA editor

I pressed “view all”, on the NLA editor, and the timeslider and numbers dissapeared from it. How can I get them back?

This only happened with the NLA editor, I tried “view all” with the ipo, action, audio, etc…and they did NOT dissapear.
I’m using blender 2.33a, winXP.
Can someone help?
