Question about the listview displaying pictures and color saturation

Hello all,

I have a listview displaying pictures.

When I disable the listview, the pictures are faded out and not selectable => OK !

When I re-enable the listview, the pictures becomes selectable ( OK ) but the pictures

do not recover de same contrast as before..? ( I would say faded at 75% , less contrasted )

What could be the problem ? No idea where to look

Thanks,

Eddy.

p.s.  :  The listview visible.false / visible.true  re- displays the pictures at 100% contrast.
