yumex not functioning on my f8 platform

[Richard England <rlengland@xxxxxxxxxxx>]

Sometime early this week I noticed that yumex on my f8 system was not 
showing any updates.   I was getting the pup (?) notification that 
updates existed but I couldn't see them in yumex.  

Today I change my  /etc/yum.repos.d/fedora_updates.repo file so I was 
looking at baseurl instead of mirror list and yumex still did not show 
any update but yum allowed me to add the 26 it showed as available.

I try to keep a watch on this list but I saw nothing about any problems 
with mirrors or yum or yumex.    I haven't touched my yum or yumex set 
up, except to add livna, and even that I did with a rpm.

What did I miss?  Anyone out there that can shed some light on what 
might have happened or suggest some diagnostics for me?

Thanks,
