Hi, I just replaced the right command key on my Macbook, and now it does not feel very firmly in place and is a bit wobbly and mushy. As far as I can tell, there is no problem with the keycap or plastic scissor underneath, but I might be wrong. I am wondering what the problem might be, and whether it is possible to fix it without replacing the whole keyboard. My Macbook is a late 2008 13" aluminum Unibody A1278, if that helps. Thanks.
