No room for a new \dimen
I have a fairly large document which uses 30 or so packages. I was going to add some TikZ graphics, so I added the following to my header file:
\usepackage{tikz,pgfplots}
However, this gave me a lot of errors of the type
! No room for a new \dimen .
After looking around, this seems to be related to a limitation of TeX. Is it not possible to use TikZ with many other packages? I am using MikTeX 2.9 and pdflatex.
