Have released a new minor version of Database Navigator.
The plugin is available for download at http://plugins.intellij.net/plugin/?id=1800
The ID of the plugin has changed so you may need to uninstall your old version if you have installed it already. The new version is not visible in the "Installed" tab of your plugin settings. Not sure if this is caused by the new ID or if it's a general issue with JB plugin repository.
A new issue-tracker project has been opened at http://www.jetbrains.net/jira/browse/DBN
Please feel free to submit any bug reports or improvement proposals to this queue. Appreciate any feedback.
