Those encountering problems with buttons with [] in the text argument
should change in cont-new.tex: 

\def\dodocomplexbutton#1[#2]#3[#4]% #3 can contain [] -> {#3} later
  {\bgroup
   \doifvalue{#1\c!status}{\v!stop}{\locationfalse}%
   \iflocation
     \resetgoto
     \ConvertConstantAfter\doifelse{#3}{\v!geen}{\hphantom}{\hbox}
       {\doifelsenothing{#4}
          {\setlocationboxnop#1[#2]{#3}[#4]}
          {\doifreferencefoundelse{#4}
             {\setlocationboxyes#1[#2]{#3}[#4]}
             {\unknownreference{#4}%
              \setlocationboxnop#1[#2]{#3}[#4]}}}%
   \fi
   \egroup}

(BTW, buttons now also honor the samepage and unknown reference settings
as found in menus)
