Can I change my odt icons?

[Todd and Margo Chester]

Hi All,

    I have both the Bug Riddled Open Office (BROO) and Lotus
Symphony (also buggy, but in Beta still) installed on my
workstation.  In Thunar, when I double click on my *.odt
documents, BROO starts as desired.

    But, my *.odt icons are Symphony's.  How do I change
my *.odt icons back to BROO?

Many thanks,
-T
