As ckcowl stated.... As a result when I work with panels, especially ones that are meant to be cut apart I won't cut them on the straight of grain but rather with the print, which while not on grain is usually a true square or rectangle (ie the corners are a true 90 degrees). Works for me because I am usually going to sash them in some way so I don't care if the edges are cut off grain. I just handle them carefully to minimize fraying.
