start wings
go to Edit > Preferences… > Camera > Camera Mode: Motionbuilder
ok
now create a cube > select a face, try to extrude (or whatever)
it with the SHIFT or CTRL constrain.
something’s wrong,
…since in motionbuilder camera mode - SHIFT + LMB
is used to pan the view, and CTRL + LMB to zoom in/out.
no such problem in any of the other camera modes. (3 mouse button)
