I have experienced a bug when using Kangaroo. When I use the pressure plugin, the geometry only exists in the perspective window. I type show all and it says nothing is hidden. It isn’t just hidden it is GONE. go to another window and try zoom to extents and it cannot find geometry. I select a point in perspective and I see the white cursor in the other three windows but nothing is there. I delete the three windows, restore them, and the geometry is back.
This happened after installing the 6.1 patch.
