directory structure - I give up

You also appear to have libraries within libraries. You should have:

Docs \ Arduino \ Libraries \ arduino_osc
Docs \ Arduino \ Libraries \ Ethernet
Docs \ Arduino \ Libraries \ String

They should not be nested.

Thanks for that.

I am showing my ignorance.

What is/was going on was I would download a library and extract it as was.

The actual file was probably nested and I simply moved it to my "libraries" directory.

I'll try to get that looked at.

Just now I am having problems with the FREETRONICS 16x2 display and getting the datasheet.
Their PDF seems corrupt, and I am trying to learn how to use it for the sake of an exercise.

Anyway, I'm babbeling now. I shall try to get the libraries sorted out ASAP.
