Re: (no subject)

hello Paul,

just looked at the example you gave and i'm really not wiser than you. 
very strange behaviour and its hard to find an answer to the question 
how its done right.
but thanks for the good report - we'll have to watch this problem 
further. i've opened a bug for it so its not lost.
