What is poi in this example? If it's a layer ID, you
must use a pound sign before it like #poi. There was a
bug is previous TileMill versions that would have allowed this
selector to work without the pound sign. There is a note about the
change in the 0.6.0 changelog.
Can you provide any specifics about the other issues you were
having? The upgrade process is meant to be relatively painless!
