- Fix more subtle bugs: - Check with long line name if the current connection is activated when adding lines to dialog or when adding lines to the preferences dialog - Use the temporary preferences context when writing the line settings - Don't destroy the mixer when the preferences dialog is closed. the new mixer will be used for the application when the preferences are changed - Pass the current selected line to the preferences dialog svn path=/trunk/; revision=51292
