"Pressure, Alpha, Contours, Invisible", NOT always available

Reporting to the last build (03Jul)

Loading Pencil will give you, as a default screen-shot, the pencil-tool as active (selected on the left Tools panel). Notice that ALL the Options on the OPTIONS-panel are ready to be selected.

Changing the pencil tool for another tool and coming back again to the pencil, will make PRESSURE and ALPHA selectable, the others grayed-out.

RESTART pencil in order to get the option CONTOURS selectable, otherwise it will stay that way.

(INVISIBLE may be operated again choosing the PEN tool)
