Does Yahoo have hard time ranking CMS sites?

[bumble]

Hi all

We are ranking well everywhere else (Google, MSN), but no where to be found on Yahoo for certain pages with a site that is managed by a CMS. Does Yahoo not like pages produced by CMS? Why would certain pages show up and not others? This is a hospital's website, so it's a credible source. Do I have to submit these pages separately?
It appears Yahoo does not have some of our pages indexed.
Do I submit them seperately?

Can anyone help? -- This message may have been cut off and the rest will only be shown to members. To become a member, click here --

I use Joomla and none of the SEs have trouble picking up new pages. Yahoo used to be very slow, but for some reason actually likes my website now (they should have liked it all along).

You can have a problem if you're using session ids. -- This message may have been cut off and the rest will only be shown to members. To become a member, click here --
