i also have a one that is 64 bit,(windows7) and seems to be almost useless.i think because most of the softwares and flashes i have compiled were written and meant to be used with xp.
so if using windows 7,you need to have a 86 bit installation to be compatible with those older files and softwares that were made for xp. the store has about a dozen computers that are running either xp or windows 7(86 bit) and all work fine with all the same programs and such but the one machine we have with the 64 bit installation wont work with nothin.
