I have a Mac Mini, iMac, and a MacBook Pro all running OS X 10.8.3 and Fusion 5.0.3 installed
The Mac Mini is a i5 with Fusion configured with Boot Camp.
The MacBook Pro is a Core 2 Duo using a virtual disk Fusion configuration.
The iMac is a i7, dual monitor using a virtual disk Fusion configuration.
When I maximize the guest OS on the Mac Mini and the MacBook Pro, it maximizes to another screen away from the desktop.
When I Maximize the guest OS on the iMac dual screen, it maximizes to the main or second screen desktop, not away from it.
I also noticed, when I move the mouse to the top of the screen, the Mac drop down minimize does not appear.
I have to use the Fusion menu View/Single window.
The configureation and Perferences are all the same.
What gives.
