Well, I've run into my first glitch with FSX. I changed the graphics toward the top end of the scale in the sim and was flying Ants Airplanes T-28A when we stopped in the water - or is that air - and I got a msg saying I had run out of available memory. I'm running an AMD Phenom II X4 940 processor using an AMD Radeon 6850 video card, 3.25 GB total memory with 2.33 GB of free memory. Time to install more RAM - if I'm going to stay toward the right side of the sliders in FSX?
