PS no longer shows Prophoto RGB profile

(PS CS2, Win XP)

I'm a little puzzled. Under Edit > Color Settings > RGB Working Space, I used to have Prophoto RGB listed along with Adobe RGB, Apple RGB, Colormatch, and sRGB. But today, Prophoto RGB is no longer listed.

I checked to see if Prophoto.icc was still in Program Files > Common Files > Adobe > Color > Profiles > Recommended, and it still is, along with the other RGB profiles that do list. It is also also in the usual Windows system folders where Windows keeps its profiles, and in Program Files > Common Files > Adobe > Color > Profiles as well.

I downloaded ProphotoRGB.icc again, and re-installed it, and confirmed that it appears in the Adobe Recommended folder, closed and relaunched PS, but Prophoto RGB is still not available.

I'm stumped.

Make sure your Photoshop Color Settings has the MORE OPTIONS enabled...

Oh for crying out load -- it was (as usual) right in front of me. I usually have "more options" turned on, but somehow it got turned off. Thanks, Jeff.

Anyone know what criteria PS uses to selects its subset of profiles when "more options" is turned off? Why, for example, it displays my Costco's printer profile along with Adobe RGB, sRGB and a couple others, but not Prophoto RGB?
