I am a retired software developer. I retired at the end of 2003 and since then my computer programming activities have been for recreational purposes. I find Mathematica excellent for that.

I started using Mathematica in 1997 (Ver. 3). I am currently using Ver. 9. Although I have used Mathematica for all kinds of stuff, I use it mostly to pursue my long standing interest in Euclidean geometry, both in the classical Greek synthetic form and in the more modern analytical form.

@JunhoLee. If you were referring to my assertion concerning approximating area, I agree it was erroneous and have removed it.

Your problem is probably specific to your installation. If it were widespread, we would have heard of it long before now.
