[pstricks] strange behaviour

[Ulrich Bongartz]

Hi,


I want to put the Text horizontally and vertically centered in the drawn 
boxes (Boxes of fixed dimensions - until now my solution). Strangely the 
first box in the source (the second highest in output) is correctly centered 
the others not. Changing the order, changes the centered line.

If I delete the \begin{center} this line also misplaced. So this is somehow 
related to the problem.

I know I could \put any text anywhere, but I would like to know, what is 
happening here.

thx in advance

Ulrich

PS: I learned from PSTricks 4te Auflage page 104 that I can set the height 
of a parbox, but this is not mentioned in "latex eine Einführung" H Kopka
