Hi Deatonent,
Oh Woa! Upon reading your post I checked ALL of my buttons. Whew! everything seems OK. Has your indevidual buttons dropped down or has the strip which they are mounted onto dropped at one end. Either way it sounds like a screw loose or something. How are you at taking these things apart - if it was me I would be going down that road to see whats going on. Otherwise a "quick trip" to your local service man is called for. Please let us know what you decide and its outcome. Jon.
