Is this happening specifically in package code?  I've noticed this kind of
thing when working with packages.  I recently saw something on the Wiki suggesting that one should use a
stylesheet other than the default.  The argument was that there seem to be
some 'issues' with the default stylesheet, but I don't believe any
specifics were given.

What OS are you running Mathematica on?

Mathematica is quirky.  I've hit several little snags like this.  I don't
have a lot of good advice to provide.  The best I can suggest is to try and
understand how things can go wrong, and look for problems in that area. 

These little annoyances can really slow down the learning process because
they lead to false assumptions about what works and what doesn't.  If we
write code that /should/ work, but it fails, we are likely to assume that
the correct usage is not correct.  OTOH, understanding what correct usage
is enables us to identify the problems introduced by quirks in the

Also, if you gain some understanding of how things are going wrong, and can
explain them, you may want share your observations with Wolfram Research.
