I'm reopening this because with Kepler-2.4rc3 under Windows 2008R2 64-bit,
when I run two Keplers and then close one, I get

Presumably, what is happening is that one of the open Keplers has the database
connection, but when it is closed, the other Kepler no longer connects to the
database.

I'm fine with pushing this off to the next release so I've marked it as 2.5.0
