Just got my 64 bit machine, but now I see that I absolutely need 32 operation for a few months to allow my software time to get up to speed. I can return the 64 bit machine, get a credit and reorder with xp pro OR I could try to multiboot. I am not a computer guru and I'm afraid of the conflicts and hools that might come up with the dual boot. Any suggestions on which direction might be the best? Thanks for being out there.
