I recently started running F@H on my iMac and iBook. However, I'm wondering, should it only run when I'm connected to the Internet, or does it only need connection when it finishes a WU? And if it finishes a WU and I'm not connected, will it hold it and transmit it later, or is it "lost"? Currently, I only run F@H on my iBook when I'm connected, just to be safe, but I'd like to run it all the time.
