Copy/Paste issue

I recently installed Debian based Netrunner on my Laptop. There is one change from the my previous (2+ years old) Netrunner version that is proving irksome. I have not been able to find any mention of the change via google or identify a setting to get back to the old behavior.

Traditional Linux includes the functionality that selected text is copied to the clipboard upon highlighting and can subsequently be pasted with a middle mouse button click. In my case this would be a simultaneous left and right button click.

This does not seem to work in my new version of Netrunner.

Is there a setting somewhere to get back to the old behavior?

Works for me. Maybe the right and left click for simulating middle click is turned off in systemsettings
