Ok. This is an awesome little program (17kB zipped or 73kB for the install program that creates the links for you)
What it does is lets you more carefully and quickly size the windows on your desktop.
For example. I like to keep my IM windows organized. So i set it to change a window to half the size of the screen and then to move it to the top or bottom of the screen.
Works well and is tiny. Only takes 228KB running on my win2k system.
I reccomend it to any windows neatfreak.
BTW. All this and more comes built in on Linux machines running the K Desktop Environment.
