In full screen mode FSUIPC freezes. When in windowed mode, I can edit it. The simulation in itself seems to be fine.
I will get FSX, I have stuck with FS9 because it has run fine in the past. I have only had this PC for a couple of weeks. So I it might take a bit of tweaking.
I have had 3 systems in the past, and it has ran with no trouble. Since buying a saitek, throttle and yoke, the need for FSUIPC has become more of an interest. I can get the PTT to work with squawk box, throught the fsuipc. Gears up and down, on one of the Saitek levers. The TOGA switch after a lot of struggling now seems to work, using the mouse macro mentioned before.
I am waiting for the new PMDG 737X to come out. I wouldn't really know which aircraft to fly with FSX, at the moment. The scenery looks amazing, in FSX.
