Hi Wolfgang,

With "aligned texts" I thought of "align={right,}]" in the above example or
text which is "flushed right":

\setbox0=\vbox{... somehow flushed text ...} wount work, i.e \wd0 or \ht0
will both result in 0. With "unflushed" text this means will work perfectly.

Sorry for the inconvinience to having been not very clear.

Rudolf
