This is covered in:
The Mathematica Graphics Guidebook
by Cameron Smith, Nancy Blachman
(see p. 106)
In[18]:=
Plot3D[Sin[x^2-y^2],{x,-2,2},{y,-2,2}, HiddenSurface->False,

Power Programming With Mathematica, The Kernel by David B. Wagner
Provides packages to eliminate the problem. It's an excellent book, and
covers this subject in great detail. Note:
This book refers you to a Math Source item that solve the problem.
Here is the quick solution:
If you evaluate
LogLogPlot[x^x,{x, 1, 10}]
before loading <<Graphics`Graphics`
Then you can evaluate Remove[LogLogPlot]. Once that is done you can
"get" the package and LogLogPlot will work.
