The lastest release works flawlessly, I didn't have to change anything other than the default windows version. I did not experience the progress bar problem that the other poster had.
I created a shell script to integrate NBPRO into a web browser. If you use a news group indexing service such as newzbin this might be useful.
!/bin/sh
"/opt/cxoffice/bin/wine" --workdir "C://Windows//Start Menu//Programs//NewsBin" --check --winver win2k --cx-app "C://Program Files//nbpro//nbpro.exe"
