I'm currently mirroring a website and want to change
the scan rules on the fly.  I open the options>>scan rules
dialog and notice that everything is greyed out except
the 3 tick boxes.  I can play with those tick boxes
to add and rule the very specific rules, but I can't
type into the rules dialog or use the Include/Exclude
buttons--caused they're greyed out.

Do I need to cancel the download to change this?
