Color Dissapears in exported SWF or Quicktime

I was working on one of my many animation projects, and i exported my movie to a .swf for previewing (as is my custom) and i saw that one of the colors was missing! I had a layer of black covering the entire scene and the black was gone! but some black color was left on a different layer. Also this this is extra weird because another part of the the the same black layer (the other part being a transparent white) was still displayed! I have exported to Quicktime (which was viewed in quicktime) and a .Swf which was viewed in Firefox, and neither showed the black part. But when i export to an AVI the black is shown! Is this a problem with Flash player, my computer, or am i losing my mind?

WTF i got up this morning and now it works. Figures.
