Dictionary in os x10.4.11

Friends:

I recently moved "everything" from my older macbook to a used PowerBook G4 and both run 10.4.11.

On the macbook I could put the cursor on any word, tap the touch pad with two fingers and up would pop a very small Oxford dictionary window, but this no longer works.

If I use Cntl + apple + D the dictionary does pop up but I would like to return to the easier method.

Can anyone get help me with this?


Thanks,
Mark

?? Ctrl, Apple and D just reveals my hidden dock!

I cannot explain this as on my machine when I hold down Control + Apple and then push "D" I get the Websters Dictionary.
