since you are up late like me i will post something for you to TRY but i'm sure the experts will be up and working angain soon and be able to answer more difinitively
I read a posting elsewhere in the Forum about using a "solid hatch" fill to accomplish what you're trying to do.
I would create a layer, color 0/white
then create either a pline or a BOUNDARY
of the object you want to remain white
then fill with a solid white hatch
then send the hatch behind the object
so whatever you put the icon over, it will always read "paper" when printing
i hope this is possible for you
or at least sends you on a fruitful search
i know what it's like to be up working when everyone else is sleeping!
