(I haven't quite Gene> made the jump to a 64 bit install, yet...) Why haven't you made the laep to 64bit yet? To me, that seems to be the real solution here, not hacks like the HIGHMEM4G and HIGHMEM64G, esp when your hardware is 64Bit by default. I've made the leap and I've never looked back. Haven't missed any 32bit only apps, and if I really needed them, I'd just load the 32bit libraries if need be.
