Icons for shared windows applications are gone in Leopard

All the icons for my shared windows applications are gone since I upgraded to Leopard. Please see screenshot. Any ideas? I've tried repopulating. It makes COMMAND-TAB pretty confusing when you can't see an icon.

 

This is corrected in the new beta version of parallels.

 

Thanks for the info. I really don't want to take the risk of installing a beta version since it would be on my "production" machine. Have you experienced any issues with the beta version?
