Most of the calculated parameters are identical between Windows and Wine, the remaining differences are sometimes minor (like round off errors), sometimes changed signs and sometimes completely different values. Running Dragon under Wine leads to a lot of fixme messages, but they seem to be related to GUI elements that I do not use.

Is this the software? http://www.mwsoftware.com/dragon/

How can I reproduce the problem if I download it?

You could try a native msvcrt.dll
