annoying line on rollup

I was wondering how I can edit or adjust a skin to remove a line (or a tiny, tiny box) in title bar when it is rolled up.  I tried adjusting the rollup height smaller but it still appears. Is it a graphic issue or is there some other adjustment.

Instead of making the rollup height smaller, try making it bigger by a pixel at a time until the box or line disappears.

That just makes the line thicker. in fact if i keep increasing it it turns into a box displaying the top part of the window. There must be some other parameter limiting how small i can make the rollup, but where is it?
