WordPress MU

Possibly a quick question, but one that's driving me nuts.

I changed the domain name I was hosting MU on, and changed it everywhere I can find in the mysql database, but it still insists on using the old domain when I hover over links and stuff.

Where the hell is it pulling this value from?!

I'm thinking it's some cache file somewhere, but can't figure out where, or how to flush it..

ta

The values are stored in the DB,

ie wp_blogs->domain table
wp_x_options->option_name='siteurl'

Yeah, changed both of those.. it's pulling it from somewhere else..

Can you do a search on the whole db?

Nope, but I looked through all the tables, hence why I said it must be coming from somewhere else.
