Window zooming when I do a "ctrl+drag" to copy a sketch entity.

I have a weird problem. I am selecting a circle in a sketch and then doing a Ctrl + drag to copy that circle. Whenever I do this my window zooms to a zoom all position. THis is new behaviour.

Is this a setting that was truned on by mistake or a bug? Any ideas on how to make it go away?
