How about this: If the corner of the top edge of the jack that's *away* from the keyboard has a pronounced edge, buff it down *a little* so it's not so sharp. This way, even if there's still a little bump in the knuckle after you brush it, at least the jack won't enunciate the bump's presence. On the rare occasions that I've done this (at a University we'll try practically *anything*) I've used a 1/2" delrin (sp?) rod or a solid piece of brass--about an inch across although that made it a little hard to get at the front edge without some strange contortions! I hesitate to admit it, but I even used a Dremel tool with one of those tiny drum sanders to take off that edge. Fortunately, the speedbumps were so severe that my dunderhead idea didn't backfire *too* badly. Well, heck! They were teflon wippens anyhow! They were d-o-o-m-e-d!!
