OSX Lion, Pathfinder + Mission Control problems

If you're using PathFinder in OSX you might see problems when using Mission Control and the PathFinder Desktop replacement.

With the last version, Mission control would not show the spaces-control elements, so you were not able to add or remove a space.

With the current version, this seems to work, but if you changed the Desktop background image, this is broken.

The Pathfinder Development team needs to improve here...

Again: this only happens, if you use the PathfinderDesktop!
