Another Photoshop CS2 dumb question

I loaded CS2 on my lovely Powerbook yesterday, and can't find the "distort" menu in "filters".

This is very annoying, as I'm experimenting with the Nikkor 16mm to use on wreck shoots, and want to try straightening out images. I have used Panotools, but the interface in CS2 sounds much easier, and makes different degrees of correction easier to achieve.

Where have my "distortions" gone??

I have only just bought my first real computer, having been PC 'til now, so I might just have been dumb...

In my CS2 on the 'non real computer' its under:

Edit -> Transform ->Disort .

In CS2 it's "filter" then "distort" then "lens correction".
