Thanks for the answer and sorry for the delay in replying. I have installed 'wine 1.3.21' and the libraries 'mfc42' and 'comctl32' via 'winetricks'. Now 'DVDSubEdit' works. Just a question for those who run this application under 'wine': Is it possible to select 'Gimp' (installed in 'Ubuntu') as bitmap editing tool? Best regards, Paolo
