Xpantastic!

Thanks all so much for the ideas. I tryed a few things. 

Reseating the board didn't work because the PCBs screw holes are actually very tight and don't allow for enough movement. 

I took a razor to the edge of a button's panel hole, but the button is up tight enough to the side that it's difficult to get a decent cut. Also, I slipped and left a small scar on my front panel. :(

For my next attempt, I'll try removing the boards entirely and filing the edges away...
