Problem with Types -> Selected objects

 From:  rado
I'm using the newest beta. I commonly like to select hundreds of objects in a scene at once and hide all of the curves that the solids were built from. I haven't used MoI consistently enough to know if this is an issue with the current beta, but there are numerous times where I have a lot of objects selected and under Types -> Selected ... all items are grayed out.

Has anyone else had this problem or does anyone know if I may be doing something wrong? I clearly have lots of items selected yet I can't choose to hide anything by type.
