Question Crown molding

During the summer and winter seasons, the crown molding pulls away from the ceiling. I was thinking of predrilling a hole and using a 3" trim-head screw to tap into the top plate near the ceiling in order to prevent it from separating. What is the best solution to repair this unsightly problem?

The reason it pulls away is that you likely have trusses in the roof which are expanding and contracting. The crown probably isn't nailed to the trusses because of the expansion/contraction factor. If it was nailed, it could split when the trusses move, or else the nails would pull out/push down on the crown and things could become even worse looking as a result.

The only solution that I could think of, would be to nail a baseshoe or similar moulding in front of the crown, nailing it to the CEILING only so that it would hide the gap but still allow the ceiling to rise and fall while not affecting the crown at all.
