Freeze when rotating many curves

When trying to rotate an imported vector PDF with more than 100.000 curves, Rhino seems to freeze as I see the blue rotating donut in Win 7 64 bit. Is Rhino actually calculating the rotation of the curves or frozen?
In other words, do I have to be patient or can I close the Rhino and try another way?

Rhino gave me the answer. The drawing is rotated now!

Thanks to 64 bit:
“705915 curves added to selection.”

Gerard, note that it was mentioned in another thread that things rotate more smoothly when everything is unselected. Not sure if your curves where selected or not…

How can you rotate an object without selecting them? or do you me when rotating the viewport?

Yes, the view. Sorry about that!
