Hi Cimteker,
In addition to adding Polish as an installed service for your PC's input language (
Start»Settings»Control Panel»Regional and Language Options»Languages Tab»Details...) you must also change the
Language for non-Unicode Programs option to Polish (on the
Advanced tab of the
Regional and Language Options Dialog box).
If you completed the first change but not the second, this might explain why you saw the text you expected in notepad, but not LabWindows/CVI.
I hope this helps!
