I believe you are talking about the windows "Aero Snap" feature. If you really want to turn it completely off, read this article, read all the way to the bottom it describes a way to turn it off, without the registry edit using the mouse settings in the control panel. Remember editing the registry can cause some serious problems if you do it incorrectly. Link Removed - Not Found

A bold what with arrowheads above and below what will appear, I think maybe this is a result of a third button click on your mouse or a center wheel click which provides for auto scrolling, just don't click the center wheel or third button
