I would love to donate for a small bit of coding.  Could you build a mouse wall similar to the mouse fence, which would leave any drop down box in windows open on just one side?  i'd love to be able to "hit the side" of a tool drop down, with a right sweep, and just slide down the right side without being able to overshoot the box.  It really would help with start-programs-, etc., but actually with anything.  Just wall off the drop downs, except for one side.  They all are connected to their parent toolbars, at the top or from the left, so you could "get in" right?   Couldn't it be done easily?
