Beware - it will show any dead pixels on your LCD - R.I.P.

I ran LCD Scrubber (limited time version) then JScreenFix all night. When I invoke the "spectrum" screen saver the line appears in during some of the colors, not all, which is about what I saw last night.

Then this morning I ran LCD test. Yes, a few dead or stuck pixels here or there, but nothing resembling a line at the top.
