There is still an issue here. \setupbars[unit=mm,rulethickness=1] AB\startbar[underbar]CD\stopbar EF\crlf \setupbars[unit=ex,rulethickness=1] AB\startbar[underbar]CD\stopbar EF\crlf \setupbars[unit=pt,rulethickness=1] AB\startbar[underbar]CD\stopbar EF\crlf The first and third setup do not give an underbar, the second does. Question: why does "ex" qualify as a dimension unit but "pt" and "mm" do not? Sounds strange. If I want an underbar exactly 1mm or 3pt's thick, why isn't that made possible? Doing the math myself is no option, becaus ex will not be known beforehand.

Still I dare say, it is a pity that [rulethickness=] gets a different meaning here than elsewhere. I would like to ask to reconsider, because I strongly believe in consistency in the API (though I am ready to admit that it is not easy to maintain and confess guilty myself at more than one occasion). That is either change all rulethickness's everywhere to this scheme or otherwise. Or did this already happened and did I miss that? And of course, the easiest solution would be if the code itself could sort out the difference between having been given a fraction or a length.
