Boolean operations?

[yaak]

I still have not been able replicate your video example There is some time lag obviously between the Boolean initiation and the Final subtraction. I don't have any input of how long this Boolean operation takes to complete. Each time I try to see if the operation is complete ........boom! the geometry disappears totally from the 3d window, No geometry remains either in the Geometry Graph window.

I'm wondering if a time to completion display bar could be incorporated in the information line, so the user can see how long the Boolean process is going to take?
