I haven't used motion for a few weeks. Everything worked perfectly last time I used it but now the
'add behaviour' and and 'add filter' icons at the top of the canvas, no longer work. No options come up when I click on them. Nothing. The particle 'make particle, 'replicate' and 'new camera' all work, but the other two don't. If I right click with the image selected in the canvas, again I can't get 'add behaviour' or 'add filter' to work.
