Yuck, behringer and a laptop soundcard, the worst of both worlds.
The behringer mixer could be causeing the bleeding, it has really bad crosstalk between the busses. When using a Behringer board take the output from the insert, the busses are way to noisy. I had the click track playing on the alt bus while I was recording off the main and everything off the main buss had click bleed through.
Laptop soundcards suck period
Make sure in your windows mixer on recording view that the wav source is turned down all they way and the only thing up is the line input.
