Photo Paint - mask marquee not visible

Mask marquee is not visible in Photo Paint. Mask -> Mask Marquee menu item is checked and Mask -> Mask overlay menu item is unchecked. The software is in default state after installation. Where is the problem ? How can I display mask marquee ? I was accustomed from another graphic programs like MS Paint or GIMP that selected area of image is indicated by dashed line. Not so in Photo Paint.
