Viewing dispatched Messages double-clicking not working.

I'm having problems in seeing the request arriving to a REST Mock Service.

I'm following the instructions in this page Working with MockServices in the section 2.1. Viewing dispatched Messages.

And when I double click the log nothing happens.

I'm currently using SoapUI 5.2.0 Build Date: 20150701-1106.

I updated to this version yesterday since I was having the same problem with a 5.0.0

Is this a known issue or am I doing something wrong?

Thanks!
