Steps to reproduce:
1. Create a Pen Mask on the image
2. Assign it to an effect (Color Key in this instance)
3. Copy and paste the attributes to another clip
4. Try to adjust the nodes in the mask:
a. Click "Path" in Effect Controls to display the path
b. Move the mouse to the program monitor and click a node
Result: .Path disappears when I click a node. Nothing changes.
Expected: Node to be repositionable.
Note: If I ctl+click a node, the node is deleted., but I still can't move them around.
