Gentlemen, I would be helpful if you sent example (small) notebooks and resulting package files to support at wolfram.com. (You may put "Attn: Bruce" in the subject line.) Special characters may lurk in code like "Which[fU T fL,..". If you have this code in StandardForm input cells, does it make a difference if the cells are converted to InputForm before saving as a package?
