Re: white tunnel in a case structure at every output
A white tunnel on an output of a case structure indicates that the tunnel is unwired in at least one case. If you're using LabView 6.1 or 7, one option is to right-click on the tunnel and select Use Default If Unwired. But I prefer to wire to the output tunnels in every case: it removes any question about what value is presented to the case outputs.

Ben: I didn't go through your code, but once your LED goes on, it stays on, even if the next time you press the button it's for less than 2 seconds.
