Two rather irritating bugs have been squashed today. The missing Menu button, forcing users to right-click on the desktop, has been restored. Also, arrow keys, page-up, page-down, and print screen should finally work correctly for all clients. Now that these show-stopper bugs have been taken care of, we’ll focus more in integrating more and more applications.
If you are still experiencing any of these issues, try removing your configuration directory first:
rm -rf ~/.config
