R help - Sep 2001 - evaluation is nested too deeply: infinite recursion?

I recently started using R (Version 1.3.0 on a Dell machine).  After using
R for about a week, I started receiving the error message shown below.
I can't even run simple commands that I know should work.  

Is this a bug or did I just mess something up? I've uninstalled and
reinstalled R but continue to receive the same errors.   

The errors are shown below:


R : Copyright 2001, The R Development Core Team
Version 1.3.0  (2001-06-22)
>  
> help(sum)
Error in as.double.default(U) : evaluation is nested too deeply: infinite
recursion?
> lm(rnorm(100)~rnorm(100))
Error in as.vector(data) : evaluation is nested too deeply: infinite
recursion?

Thank you very much for considering my problem.

A Dell machine running Windows? (As opposed to the Dell running Linux
which I'm currently looking at.)

Hum. Something like this might happen if you set
options(expression=25) or so. Might something like this be lurking in
a workspace you load on startup?
