Before upgrading to Snow Leopard I could right click on a PowerPoint file and choose to open it with the Windows version of PowerPoint. Now I only see the Mac version of the app. I have tried turning Share Windows Applications with Mac OS X on and off and I have turned Enable SmartSelect on and off. I chose Populate under Shared Windows Applications. Oh, and I reinstalled Parallels 4.0 build 3844. So far I haven't had any luck.
