The automatic skin detector works by finding skin near and of the same colour as the face you have marked up. That's why it doesn't work when you are in skin only mode. Try enabling the "skip to last step" button (in settings) and quickly do the first 5 points then press the fast forward button. That might get you to the result you want the quickest because it can automatically find skin from the little information you give about the face, but doesn't require a full markup. The skin only mode is mainly intended for cases where there isn't a face in shot.

As for crashes, open a support ticket and we can see if we can reproduce then fix them.
