Palm Desktop Background and Rosetta

I recently upgraded to OS X 10.6.8 (Snow Leopard). When I start up my Mac, I get a mesage that says "To Open Palm Desktop Background, need to install Rosetta." I think this is related to an old Palm product I used to have but no longer use. Within System Preferences > System > Accounts > Login Items -- I have taken the check mark out of the box next to Palm Desktop Background. Anyone know what else I need to do to eliminate this message whenever I start up my Mac?
