Is it possible to put a \cite command in a \caption?  LaTeX is giving me an
error when I try it, and I cannot seem to find an answer in either the LaTeX
manual or the list of frequently asked questions posted monthly to this
group.

Basically I need to put a bibliographic reference in a figure's caption, say
like this:

   \begin{Figure}{htb}
   \centerline{\epsfbox{fig_cpu_flow.ps}}
   \caption{From \cite{Hayes88}, the typical cycle for a serial CPU.}

but LaTeX seems to complain about the extra braces:

   ! Argument of \@caption has an extra }.
   <inserted text> 
                   \par 
   <to be read again> 
                      }
   \addcontentsline ...\protect \contentsline {#2}{#3
                                                     }{\the \@temptokena }}}}\@...
   
   \@caption ... the#1\endcsname }{\ignorespaces #2}}
                                                     \begingroup \@parboxrestor...
   l.459 ...e typical cycle for a single serial CPU.}


Pardon me if this has an elementary solution.
Mike
