Cannot see Log Messages tab in Calc Manager after running a groovy rule?

Summary:

When I run a groovy rule in calc manager I am not getting the Log Messages tab pop up but would love to be able to see these sorts of statistics.

At KScope this year I saw a presentation where they were showing that calc manager will typically show a Log Messages tab after running a rule within Calc Manager. This appears to have a bunch of useful information included but I can't get this to pop up when running a groovy rule. Is there a way to get this type of information?
