Keyframes in Action Editor Not visible

The keyframes in my action editor have suddenly Dissaperared… maybe did i press a button…
or blender is as buggy as ever ??

In 2.49 you can move the keys up or down out of sight . sometimes without noticing you have done this . With shift alter .If it went left or right you should see a timeline shadow. 2.5 has a scroll bar.
I think you got the wrong animation forum , support is below . I did the same thing yesterday.
Hope you find your keys.

press the HOME key.
