Messages window not available

/uploads/kotlinlang/original/1X/9e254d8ec04a58ee4bce5ae5d3adec9dc187016c.png

The Messages window menu item is disabled, so the only way I can see the compilation errors are with tooltips, which is annoying (and which also makes it hard to copy/paste errors to report problems).

Is this a known issue in the current plug-in?

For future reference:  http://youtrack.jetbrains.com/issue/KT-1622  (run a build to make the messages window appear).
