i saw that someone sort of answered this question partially back in july but is there not only an updated list but somewhere to find an expanded list to cover 64 bit compatiblity-- i have noticed that when products say vista ready or compatible they usually mean 32 bit not 64 -- and sometimes this makes a difference -- and sometimes old programs like ad aware go from being compatitble to not being compatitble --or like quicktime/itunes that i was initially able to install and now i can't do the upgrade to the latest version --- so where can i find out which ones i can use
