I have the following Tikz picture:
\begin{tikzpicture}
\node (a) {A};
\node [below=2cm of a] (b) {B};
\end{tikzpicture}
When I compile this code with PDF-LaTeX, I get the expected result: "B" appears 2 cm below "A".
When I compile the exact same code with plain LaTeX, in the DVI file, "A" and "B" are in the same position, mashed together. In the PS file, after another re-compilation, they appear correctly again.
Is there some way or workaround to work with PGF/Tikz with positioning straight with the DVI preview?
