Class Browser and Code Sense not fully working

Since I upgraded to XCode 3.0 the Class Browser is not longer showing 
frameworks methods, and also code sense is only showing methods from 
my own project.
I am not able to figure out what setting I should change to remedy 
this. I have XCode 2.5 installed alongside 3.0 and it does not have 
this problem so it must be something related to 3.0 or my settings. 
Any help will be appreciated.
