Before I upgrade to Lion from Snow Leopard, I want to know if I'm going to have to reinstall Fusion, Windows, and my Windows apps (Quickbooks and Quicken). Does the Lion upgrade mess with the Fusion partition? If I have to reinstall Fusion do Windows apps remain untouched? In an ideal world I'd switch to the Mac versions from intuit, but in my experience they are not nearly as good as the windows ones. Can anyone help me out here?
