Hello

I'm the author of TKZplot2d but i'm also a mathematics teacher ans i
work this morning but in  a few hours i can give you the solution.

First look at your files (tikz/pgf)

http://pgf.cvs.sourceforge.net/pgf/pgf/generic/pgf/utilities/pgfutil-
common.tex?view=log

You need this one (above) is from cvs
