I think it is the locking pin causing it to get stuck. I had it happen a couple times before, but this time it was really, really stuck bad. The button gets stuck pressed in and will not go back up unless you poke it from below. The alcohol soak helped get it unstuck and usuable again, but it still sticks sometimes still. I am going to soak it again and give it some hot water then try and get the button out so I can remove that locking pin for good. Looking forward to more Reos going on sale soon, I really need a backup so this doesn't happen again. I may have to send it back to Rob to get a new button as I messed it up pretty bad with some pliers trying to pull it back up again. This was before I realized I could poke it up from below.
