emplode b7 pushing down too many times

I noticed that if you push the down playlist button too many times (past the last playlist index), the program will crash. Also, there seems to be a hidden playlist that consumes one of the index numbers.

This is a known problem. The 'hidden' playlist is the "Unattached Items" playlist. The move up/down buttons only crash emplode if you do this in the root playlist.

As soon as I figure out a good fix, it'll get fixed.
