Remove flashing selection halo when editing in place

Hi,

When I am editing in place a layout cellview, I am experiencing a stall/delay in performance everytime the cellview’s flashing halo changes from bright to dark. Is there a way to remove the alternation in the selection halo, so that it remains a single colour? I’m using IC6.1.6-64b.500.8.EHF1167

Thanks,

Brian.
