strange dependency between cbox and whitespace?

strange dependency between cbox and whitespace?

[Stefan Wachter]

Hi all!

I came across the following behaviour: cboxes seem to suppress white 
space in certain conditions.

In the following example there is no whitespace output between paragraph 
no. 2 und 3. Yet, if I change \setupwhitespace to 'none' or if I do not 
enclose the paragraphs in cboxes then the whitespaces between the 
paragraphs appear as expected.

Does anyone know a workaround for this 'strange' behaviour of cboxes?

Thanks for your attention,
--Stefan


\setupoutput[pdftex]
\setupinteraction[openaction={firstpage,FitHeight},state=start]
\setupwhitespace[small]
\setupblank[100pt]
\def\Para#1{\cbox{#1 \dorecurse{10}{this is some paragraph text}}\par}
\starttext
\Para{1}
\blank[big]
\Para{2}
\blank[medium]
\Para{3}
\blank[small]
\Para{4}
\stoptext

has to do with the way tex handles vbox/vtop's (tex does not have dual 
baseline boxes)

\def\Para#1{\cbox{#1 \dorecurse{10}{\begstrut this is some paragraph text 
\endstrut}}\par}

or something:

\long \def\Para#1#2\EndPar{\startalign[middle]#1 #2\stopalign}

Thanks for the reply. I am using the \startalign option now.
