I dont imagine that that is supposed to happen. One of them using about 1900kb, one using about 5500kb. I admit I have not read the documentation yet, or poked around the computer. I figure if it happened to me it probably happened to someone else, so I would try here first. just installed it this week. downloaded the free, then upgraded to the 1 house license. at present it is installed only on one computer which is behind a router. XP-H-1, 1 GB ram, Pentium 4. Is this fatal? - HandsOff!
