Check names not working for multiple address books / contacts

Hello!

I have upgraded from outlook 2003 to outlook 2007, my contacts are stored in
pst. I used to be able to search for a name via check names and it displayed
me all the results from global address list and from my contacts, but now it
only does one. It does not matter which one I set in the checking order,
whichever is top will be the one that provides the result. I would like it to
show me both results, how would I go about to set that up?

Thank you

Deana
