Show Value In Editor not working in Python Project

Hello,

I have a license for IntelliJ IDEA 14.0.3 and I use it a lot for Python work. Currently when I debug a Python project I don't see the variable values in the editor pane even though in the Debug options I've checked "Show Values In Editor".

Am I missing something? Is this not possible with IntelliJ and the Python plugin? I'm using plugin version 4.0, build 139.129 (which appears to be the latest version).

Thanks,
Craig
