Adjustment Pins not showing in Camera Raw after updating to latest version?

Hi since the last update to camera raw the adjustment pins are not showing for the adjustment brush. I can make adjustments but if I want to edit them later I am not able to see the pins.

This has happened to me before and I had to upgrade to a newer graphics card. I have openGL switched on and graphics accelerator is checked. I'm operating on an Early 2009 Mac Pro 48gb Ram with Graphics Card AMD Radeon HD 7950 with 3072 Ram.

Can anybody help? or is there a way I can revert back to the previous version of camera raw that had no issue with this?
