I've heard that Windows 7 is almost perfect in compatibility mode.
hmm........ I simply installed AH just as one would install AH in windowsXP.....I do not run it in any type of compatibility mode in windows 7 64 bit...........( nor in Windows XP )
also Windows 7 64 bit has not required any hotfix patches from MS nor has it required me to install AMD's optimizer patch for Dual core processors.....
least that is how my systems ( OS's are running )
others may have to use the compatibility modes........
