Why was this a bug report?  It does not seem to me to meet the requirements
of a bug given in the R FAQ.

Not on my machine: that command works for me.

What do you (John) expect this command to do? In particular, what directory
does you expect it to list?  You have not told it, and Windows has quite
complicated rules for finding the current working directory. My guess
is that those rules are giving a: in your circumstances. Put a floppy
in and find out.

Tip:  using shell() would be much simpler. Try ?shell (on Windows only).
