VMWare Unity on Windows 7 RC (Host) with Ubuntu 9.04 (Guest)

I'm currently running the Windows 7 RC and trying to use VMWare Workstation's Unity feature with a Ubuntu 9.04 guest. Unity starts, and I can access the Unity "Start Menu" for Ubuntu within Windows, but when I launch an application, it does not appear in Windows. Interestingly, if I exit Unity, all the apps I launched (which didn't appear) are open within Ubuntu. Does anyone know how to get Unity working on Windows 7 RC?
