I see ...

Still not quite what I'm looking for ... my problem is that the  
columns environment doesn't align correctly, even with column1 +  
column2 < totalwidth:

\documentclass{beamer}


\begin{document}


\begin{frame}
     \frametitle{Title}
      \begin{itemize}
        \item Fruit: apple, banana, pear, strawberry, raspberry,  
blueberry, pineapple, tomato
            %\rule{\linewidth}{.4pt}
            \begin{columns}[t]
                \begin{column}{.45\linewidth}
                    Enter text, formulas or pictures into the left  
column
                \end{column}
                \begin{column}{.45\linewidth}
                    Enter text, formulas or pictures into the right  
column
                \end{column}
            \end{columns}
        \item Vegetable
    \end{itemize}
\end{frame}


\end{document}

I'd actually like "Enter" to be left aligned with "Fruit" and  
"pineapple" ... I don't mind about line breaks, I'm rather perfectly  
happy with two columns with the same static widths side by side.

Any idea how to get there?

Many thanks again,
Oliver
