Bizarre Quicktime bug

Maybe related? Yesterday I saw the QT picture viewer 'adding' garbage/ 
left over images to the transparency layer in a PNG when viewing. The  
garbage has nothing to do with the PNG and it is not happening to all  
PNGs, just most of them. The PNGs look fine in every other program  
that does not use QT for viewing. Nothing to do with flash drives or  
movies but it seems there is an issue in Vista with QT.
