Mac beta - enabling VRay kit breaks UI dropdown menu functionality

[YabbieSandwich]

When I have the VRay kit enabled in Modo, the Modo UI dropdown menus stop working (click and hold any of the UI buttons with the small black triangle in the bottom right corner). Disabling the VRay kit makes them work correctly.

Modo 701 SP5
Mac OSX 10.10.1

I can confirm that. It must be something with the VFB UI we create inside the MODO application somehow disrupting the MODO UI.
There is the workaround of right clicking on the button, instead of holding the left mouse button, but aside from that I am not sure what can be done.
