just noticed something very odd.
im running window blinds, i removed the interface so its normal windows xp.
lw runs smooth as a baby.
very wierd.
i tried other windowblinds interfaces, lw runs fine.
finally went back to the interface i like, and lw is choppy again.

thus the problem is a windowblinds interface called ares.
come with the program, not sure if it comes with the free demo.
