The latest change to make the values editable by CTRL+LEFT MOUSE CLICK is not working on a MAC / OSX Computer (only tested in firefox but that should be the same problem everywhere). On Macs the STRG+LEFT MOUSE is hardlinked in the OS to open the context menu.
I did not read why that was changed. I liked the double click actually. Please select something else for editing or make it using "command + click" if the browser is on a mac system!
