I don't want to defrag the disk, I schedule that every night, I want something that cleans up memory, the O/S is as leaky as hell from what I can see I want something that will return memory to the "free" pool once it's been used. There are quite a few such utils for the mac, and UNIX doesn't need them, but I figure somebody must have written one for the PC... As for 98, I'm running a fully patched release 2. I don't want to run NT because half of my apps will stop running and W2k is a joke, it runs 20% slower on my machine, due to its pathetic attempt to keeps itself afloat. Supposedly they included technology to stop you having to reboot every three hours, but this involves a lot of internal plumbing that has to keep watch on itself, hence the slowdown. later jb
