 Hi,
 
 I get the following resuts, which are not very useable, I think. If the 
 problem is only reproducable on my machine, maybe we should leave the 
 matter, so you can spend more time on things that are useful for more 
 people. There is a simple workaround, so I am not really bothered by 
 this.
 
 \Gr, Otto
