Here's my screenshot, and while I'm trying to add Mask 2 to my little spaceship(the dark green quadrilateral mask), the cursor is not a just pen, it has a plus sign next to it, it's the cursor for "Add Vertex Tool" although I choose "Pen Tool". And I don't know how I enclose the mask, and then I go to the mask property, try to change the feather, but nothing happened.
How do I appropriately add second mask to my object?
Uninstall CC 2015, install CC 2014. that feature somehow is borked. Something to do with high-DPI displays and cursor precision...
