Desktop Icon Positions

[Smith, Herb]

Hi all,

My recent install of FC5 went fairly well.  I have one behavioral issue
that, while minor, is a bit annoying.  The "computer", "home" and
"trash" icons on the desktop will not stay where I put them.  If I log
out and log back in, they get moved to some other (always the same..)
locations.  The icons associated with launchers that I create all behave
as expected, as do the Firefox and Thunderbird icons. 

Has anyone experienced this behavior?  Is there a way to permanently
change the default position of these system icons? 

Thanks in advance.

Herb
