Fs SkyWorld 2004?

Hey everyone , I just wanted to know if it's indeed recommended to run Fs SkyWorld.exe in compatibility mode with Windows XP SP2 & as administrator like the FS9.exe itself under Windows Vista?
I mean it would'nt hurt to tun it on Windows XP compatibility mode would it? as that is how my FS9 is set.
