Getting F&H text client to downld multiple WUs

What setting do I use, or which version of F@H do I need to be using, to get F@H to download multiple work units?

I have dial-up at home and my main rig chews up these WUs in a matter of hours. I don't want to waste good CPU time idling!

I'm running two instances of F@H on a HT Prescott.

Thanks!!

If you are already running 2, that should be fine. FAH is not like SETI where you can download WU's to work on later, they are rather time sensitive. You could add more instances, up to 8 but that is it.
