RSTP not so Rapid

I have 3 Netonix switches configured in a ring:

A---airfiber5----B---fiberOptic----C----airfiber24----A

RSTP is enabled on all of them with a Max Age of 20, A Hello Time of 2, a Forward Delay of 15.

When one of the links goes down (e.g. the airFiber24) it takes upwards of 2 minutes for the traffic to re-route.

What can I do to speed this up so that spanning tree is actually rapid?

Please a picture of the STP tab for at least one of the switches.

Any ideas?

What I'm thinking right now is that maybe the root is bouncing around a few time's which causes the delay. So possibly changing the priority on the root to solidify it's position so that when the link goes down and up again it is obviously a much higher priority might help. But I'm still trying to prove that in my own setup.
