When I type R I do not get the simulation rate menu. In fact, nothing happens. I tried assigning this function to a controller key. Still nothing. I have just installed FSX (boxed DVD edition, still in shrinkwrap), with both service packs into an HP desktop running double quad CPU, 64 bit, with Windows 7 Pro. I ran FSX Acceraration years ago and I changed the sim rate to 8X often. Any suggestions? Thanks, Paul
