Comment 2 thadguidry 2010-07-02 02:50:18 UTC

After removing the Scala_Home env var, restarting Windows 7 and resetting the SCALA_HOME env var to "C:\User\Thad\Downloads\scala-2.8.0.RC7" , the interactive console (REPL) now appears to work correctly inside NB nightly with Scala 2.8.0 RC7 available at command.  Weird. The only thing I can think of is that the user environment variable needs a true restart of the OS to take effect in Win 7 ?  -- THAD
