I agree with that. I have 384mb RAM on my development machine (more than most
people have of ram+swap combined) and NT -still- whines and bitches if it
doesn't get a swap file. It wants swap and will use it regardless of physical
memory, like it or not. I think if I put 2 gigabytes in the box, it'd -still-
swap to disk. It's just the way the OS (both Windows and NT) is designed.

In light of this and the other comments in this thread I guess I will
begrudgingly accept the current system for what it is. It doesn't mean
I have to like it though.

Windows is a memory hog.   i can't run this Sci-fi scene with out running out of
memory (P120 w/24MB RAM and 570 MB free HD) the objects themselves are over 70 MB.
and my HD free space drops to 330 MB and everything else slows to a crawl.....  BTW
the scene aforementioned is mostly made up of UDO meshes

	Don't try to understand why but what it is doing is loading up
all kinds of DLLs and other files that are used in the boot
process (at least, maybe some other processes) and leaving them
resident. 

	This was recommended to me for another problem

	but it didn't help for that one. It might work for some other
problems.
