Upgraded Thunderbird for 1.0 to 1.5 and no icons

["Robert Moskowitz" <rgm htt-consult com>]

I am running Centos 4.3 and have added Centos Plus to get Thunderbird 1.5

I did the install and now Thunderbird is without any icons.  I rebooted 
and still no icons.

When similarly upgrading Firebird, a log out/in enabled the icons.

Now one interesting point is when I use Nautilus to access 
applications:///Internet the launcher for Thunderbird is:

mozilla-thunderbird

This was the case for 1.0, but not 1.5

I created a link /usr/bin/mozilla-thunderbird but still no icon (and of 
course I am running TB from a script).

How do I get icons working?

I have tried going into properties for the TB launcher, but cannot 
change it.  Even as root.

Additional question with launchers.

I kind of understand drawers, but I liked how I was able to easily alter 
my start program menu in XP/W2K just by putting shortcuts in the proper 
directory....
