Windows Remote Desktop goes behind Mac menubar in Coherence mode.
Remote Desktop always catches the whole display in spite of workspace or any menubars (Mac menu bar and Dock). The other applications windows are cut off by Mac menubars, but it is impossible to cut off Windows Remote Desktop window.
Do not stretch the Windows Remote Desktop window to the full screen when you run your virtual machine in Coherence view mode.
If you want to stretch the Windows Remote Desktop window to the full screen, switch your virtual machine to the Full Screen mode.
