Hello All,
Yes, the material below was discussed a long time ago, but at that time I did not follow what was going on, but kept the message thinking that some day in the future it would be of interest. Well . . . that day is here! ;-)

I don't follow Alan's comment "Make sure it's after the \counterwithout command." because on commenting out the \counterwithout command, Alan's code typeset as George wanted. Also, on commenting out the line <\usepackage{chngcntr}> as well, the typeset was correct!!!
However, since George wants chapters numbered as I, II, III, . . . I used the following preamble to obtain the desired form:
\documentclass{book}
\usepackage{amsmath,amsthm}
\theoremstyle{plain}
\newtheorem{theorem}{Theorem}[chapter]
%\usepackage{chngcntr}
%\counterwithout{theorem}{chapter}
\renewcommand{\thetheorem}{\Roman{chapter}.\arabic{theorem}}
\renewcommand{\thechapter}{\Roman{chapter}}
Could not find anything about \counterwithout nor \usepackage{chngcntr} in The LaTeX Companion nor did the bash shell turn up anything via $texdoc .... However, on commenting out the \usepackage{chngcntr} line but leaving \counterwithout intact, the error message was that "\counterwithout was an undefined control sequence" which makes sense.

I have this uncomfortable feeling that, once again, I'm missing something!
