I just want to add, about the memory leak; FSX was using up to 3.5GB of RAM and with no other changes except disabling FSX power project memory usage has went down to the 1.3-1.5GB range. This is with GEX, REX, UK2000 EGLC and EGLL, PMDG MD-11, and much more than I can remember off the top of my head.
