Frozen grain with Mokey Remove

Hi,

I have a couple of grainy shots where I have to remove wires.
I would like to use Mokey for this, but in the results I have got the grain freezes in the removed area.

Is there a work around for this?

Is it for instance possible to sample a couple of frames to generate grain in the cleaned area?

I´m running Mokey 4.1.4.

Kind regards

Thomas
