Windows 7: anybody using Desksoft WindowManager?

if you don't know what it is, basically it's a program that can remember
every window position and size, a thing that has been disabled in 7 unfortunately.



the thing is, with program like winamp it can cause some trouble
so what im asking is, is there a way to disable the program completly for some programs or windows?
all i need is basically just 2 windows to customize but the program default is to control all windows and programs.
