Hi! I'm from Brazil and vDos was really a miracle in my life, since I could run Clipper programs in Windows 10! I know it's difficult to believe that someone still uses Clipper nowadays, but I do! vDos is great and I'm very thankfull! The only problem I'm having is that sometimes when I'm running the programs the message "Ret from illegal descriptor type 0" appears and I have to close the window. Some suggestion regarding this?
