Does Parallels work on Leopard?

I am not sure if you guys have begun development on a version for Leopard yet but I just installed parallels on Leopard Build 9A303 and tried to run one of my XP guest and I get the following error "Unable to communicate with hypervisor". I guess I should know what my answer should be but just in case you are developing here is my first bug to submit to you.

 

Which build of Parallels? I believe the latest build is supposed to be compatible with Leopard.

 

1970 is the build I have

 

Nevermind, I did a restart and everything worked fine with Parallels. Thanks
