I did the same thing to my SB. When I took it down to Altsmoke (I live 45 minutes away) and asked about repairing it, they told me it would only be $10 but it would take a while for them to get it done. I didn't want to be without my beloved SB for any length of time so I just keep prying it up with some pointy tweezers when it gets pushed down again. One of these days I'll get it fixed, but in the meantime it still works just as well otherwise.
