New to blender help with draw keys

I am new to Blender and I am currently working through the Essential Blender book. But I am having trouble with the Draw Key function. The book says that when I press the k-key that the keys will be displayed in an olive color but they appear in yellow and of course selected. I figured I could deselect in the IPO window but every new key I add after that remains selected, even after I move to a new frame. This makes is impossible to work on new frames without altering old ones. I can work around this but, it’s a hassle. The book made to seem really straightforward. So my question is “what am I doing wrong, and why are the keys remaining selected?”

I’m working in blender 2.48 on a Mac osX 10.4

Press “a” to deselect/select all toggle. That should fix your “old” key selection problem.
