I had a problem with a couple of drawers coming open on a trip. I removed the drawer and figured out what was holding it closed, a small dent at the end of the guide if I remember right, it'd been over a year. I increased the dent some with long nose pliers, doesn't take much. If you go too far with the dent it makes the drawer too hard to open, ask me how I know. A little tweaking and all works well and stays closed while traveling.
