yumex won't skip checking for updates

[Robert Moskowitz]

In preferences I have unchecked 'autocheck for updates', but everytime I 
start yumex, it checks for updates.  Then I have to click on 'Available' 
and wait again as it does its think before I get the list of all apps so 
I can search for whatever I am looking for.  Quite a rather unpleasant 
experience.

So how do I set yumex to skip checking for updates and just go to what 
is available?
