Middle click drag & drop to create link?

In Mint on Mate 1.10 I used to be able to drag a file while holding the middle mouse button and when I dropped I would get options to copy, move or link the file. What happened to that functionality? It seems the mate-mouse-properties is missing an entire second tab as well?

This functionality still exists and works today, it sounds like there is a configuration problem. Is this with a mouse or does your hardware “simulate” a middle click (ie. Left + right pushed together on a touchpad?)

regular mouse. strange. any ideas on fixing this? i’m clueless.

Ach! So sorry. A reboot fixed it.
