[NTG-context] Arranging problem / texexec--arrange

Hi Hans, While trying the possibilities to arrange pages I detected, that using the predefined European standardsizes of the pagesize and the sheets arranging works well. However if I try to use a custom size paper on a standard sized sheet, then I see, that the different pages do not seem to be positioned correctly. When using the option --arrange with texexec, Context halts after loading the basics. You can show this problem with the testfile I attach to this mail. Would you be so kind to have a look at this. I need to prepare a booklet, where I have to use a custom size pagesize. For the demonstration of the problems I attach a test file. Kind regards Willi
