I just recently purchased a Venom Pro Charger, and it is going back for a refund. The software with it is not compatable with windows vista, even though the manual says that it is. Tech support for Venom straight up said it was not compatable with vista and had no clue the manual said it is, go figure. Does anyone know what chargers that come with analysis/graphing/control software are compatable with Vista? I currently use NiMh, Li-ion, LiFePo4, and sla's so it needs to work with all if I'm going to spend money on it. I'd prefer not to break 200 dollars on one if possible.
