hey guys… Version 7.5.5 (b1255), Java version 7u11 The problem of being in the designer in preview mode and then clicking on a component in the project browser, other than the root container, still exists and generates the javax.swing.JComponent error The error window is no longer popping up, but this error still shows up in the console: `Exception in thread "AWT-EventQueue-0"

There is already a bug ticket in our system for this, we’ll update this thread (and [this](http://www.inductiveautomation.com/forum/viewtopic.php?f=72&t=8861) thread) when the bug is fixed. ---
