Howdy,

Hmmm... I'm not having a problem. I put 

\begin{tikzpicture}
\foreach \n in {1,2,3,4,5}
	\fill [red] (\n, 0) circle (2pt);
\end{tikzpicture}

into a document and it typesets fine. I Copy/Paste into the Edit->Experiment… window and press its typeset button and all is fine. I then change the \foreach range to {1,...,5} and press the Edit->Experiment… window's typeset button and all is fine.

I'm using a fully up to date TeX Live 2015 (although that shouldn't matter) and TeXShop 3.61.

Good Luck,
