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. My main reason for joining StackExchange is to participate in Mathematica.SE. I enjoy answering question when I can, but I also enjoy working at making the site a better place to visit.

I started using Mathematica in 1997 (Ver. 3). I am currently using Ver. 10.0.2. 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.

It's a nasty bug. I've run into it, too. What you did -- saving your work into a new notebook -- is the only work-around I know.

What version of Mathematica are you using? In V10 on OS X and, I think V9 as well, the default value for $RecursionLimit is 1024.
