[Squirrel-sql-users] Error occured saving Alias Definitions java.lang.NullPointerException.

[Bresnahan, M. <Mic...@be...>]

I am receiving the error "Error occured saving Alias Definitions
java.lang.NullPointerException." when I exit Squirrel SQL Client. =20

I downloaded Squirrel SQL Client 2.3final, configured the Oracle Thin
Driver, created an alias, tested my alias, and then clicked on File ->
Exit.  I then received the following error.  After restarting the app my
alias is gone.  This happens every time.  I am using Windows XP SP2.
