"No show" cookies

I seem to be having an issue with cookies not showing up in the Options/Cookies area and it started happening after I updated to Firefox version 3.5.2. I have checked my privacy tab under the browser's Tools/Options/Privacy tab and it is set to accept cookies. The cookies show up in the "show cookies" area of the browser, but NOT in the cookies area of CCleaner. FYI: cookies DO show up in the Options/Cookies area if I use Internet Explorer-7 (IE-8 has issues with my machine.)

Windows XP Pro, SP-3

Firefox version 3.5.2

Internet Explorer-7

I'm stumped,

Tom
