Re: vertical alignment problem in column items

[Otared Kavian <otared@gmail.com>]

Hi Dalyoung,

I think that there must be a small bug in mkiv regarding itemize in columns, but at the same time I think that the problem comes from the fact that in your example you use inline maths and fractions: this perturbs the way the horizontal and vertical distances are calculated by mkiv. It seems that mkiv considers there is not enough horizontal space to put the four items in a row.
If you use two columns the problem is solved, as you can see in the following examples (please typest it both with mkii and mkiv to see the differences).
Best regards: OK
%%% begin itemize-dist-bug.tex
\starttext

\setupitemize[1][n] % first level itemize

\setupitemize[2][a,paragraph,columns][stopper=)] % second level itemize
%If you want more than two columns by default add "n=x"

\startitemize
\item Item one
\item Find a well-ordered set:
\startitemize[n=4] % <--- gives correct output both in mkii and mkiv
\item sub-one
\item sub-two
\item sub-three
\item sub-four
\stopitemize
\hairline
\startitemize[n=4] % <--- gives correct output in mkii, but not in mkiv
\item $\{ 2 + \frac{1}{n}, n \in\naturalnumbers\}$
\item $[0, 1)$
\item $\{3 - \frac{2}{n}, n \in \naturalnumbers\}$
\item $ \reals$
\stopitemize
\hairline
\startitemize[n=4] % <--- gives incorrect output both in mkii and mkiv
\item $\{ 2 + n^{-1}, n \in\naturalnumbers\}$
\item $[0, 1)$
\item $\{3 - 2n^{-1}, n \in \naturalnumbers\}$
