Thanks Bernd. I'll look at GridDrawer. I didn't even know about the grid until I started messing with this problem--didn't know why when you drag controls around they seemed hard to position exactly--they were snapping to the default 2-pixel hidden grid.
And Ender--this is great. Thanks!!!! I made modifications to the script (modified stack is in the forum) for my particular application (I'm working with rows of buttons): http://forums.runrev.com/viewtopic.php?f=22&t=18910&p=95304#p95304 1. buttonActive snaps to buttonListener--buttonListener never moves 2. Once snapping has occurred, buttonListener still doesn't move 3. I've removed the snapping to tops and bottoms--I don't want that for what I'm doing Now, can there be multiple listening buttons? I'm thinking that while the active button is being dragged, it periodically checks a list of possible listening buttons to see if any one of them has met the close enough criteria--then designates that one as the listener. This would allow me to lay in rows of snapped buttons.
