[quote="jeffz"] Is this the software? http://www.mwsoftware.com/dragon/ [/quote] No, this is a link to the correct software: http://www.talete.mi.it/products/dragon_description.htm, it is unfortunately commercial (I have not tried with the evaluation version). [quote="jeffz"] How can I reproduce the problem if I download it? You could try a native msvcrt.dll [/quote] Thanks for the msvcrt.dll tip! I will try and see what happens. If this does not help and the same problem occurs with the evaluation version I will post the input files on this board. Christoph Helma
