I recently bought a Novation BassStation second hand. Everything is fine except the panel being a bit loose. I suspect that it has to do with a screw on the side of the panel which also seems loose. Unfortunately i have never seen this kind of screw before - they're hollow with a notch in the thread!? - so i thought that some of you might be able to help me? This is the screws and the loose panel:



you can click the pictures to view them as large ones. BTW the battery is just to add some sense of scale
Thanks in advance for your help - it's much appreciated!
