Could you let us have a small set of files set up like your document as well as a description of the order you are doing things to see the behavior. Does this happen if you open the root file directly? What are your `Project Root File' settings (TeXShop->Preferences->Misc)? Etc.

Howdy,

After correcting the name of the included file (the one in base to agree with the name in the \include statement in root) I can open and typeset each file. I also get syntax coloring on both file independent of order of opening them.

By the way, I don't see how TeXShop knows that there are multiple files if you open the root file---it doesn't look for \input or \include statements---so it looks like any other .tex file (i.e., no special `% !TEX' commands). And you say it isn't syntax colored if you open it first?

Good Luck,
