I guess because it's parent is a column.
It doesn't seem to really respect the Visible setting, even if you explicitly set it to .F. It acts like it's ReadOnly.

>I was wondering why the checkbox is visible, but readonly, when I don't include the ".visible=.t." code. I know that VFP hides controls added with ADDOBJECT(), but why is it visible if I leave that command out? Shouldn't the box not even show up?
