"they remain HIDDEN". Ah, now that's very strange! By "Omni" I guess you mean "Infinite", Poser 4 don't have omni lights. If CL are using the term correctly "infinite" would imply that all the "rays" are parallel, and that the light is the same intensity at any distance. An omni light is one that spreads out in every direction (much like a light bulb). Poser does not have omni lights you have to build you own by making a globe with several spotLights that point out in diffrent directions. Getting back to the ankle shadows, another factor that affects this is wether the thing receving the shadows has "Casts Shadows" enabled. I would not of thought it, but Casts Shadows not only affects wether a thing casts shadows, but also how it receives them.
