...but today, during a moment of extreme madness, I loaded up my FSX, connected to Multiplayer, (via the fantastic FS Host Client!), gave ATC a call, requested "Flight Following", and for the first time I was able to Fly in Multiplayer and contact ATC for the first time...
...., (It cant be done in FS 2004... 
...)!But the thing I miss, really miss!, more than anything else, is my wonderful FS Navigator, with all its amazing, real-time information (including Radar) appearing on screen as I fly!
It was never produced for FSX.
Although my Comp spec is fairly lowly, (Pentium P4 Dual Core, 2.8 GHz), and runs FS 2004 beautifully, it can run FSX with most of the sliders moved up, and although it is slightly "stuttery" in busy places, it is fairly acceptable.
I could/may be persuaded to move over to FSX more, if only I could take my wonderful FS Navigator with me!
So at the moment I run both FS 2004 and FSX, selecting which one suits me better at the time!..
...!Being able to use full facility of; "Air Traffic Control" in FSX Multiplayer, is a big advantage for me!
