Well I never! Drag and drop does work! At least in Win98 - haven't tried it in Win95...You have to create a shortcut to the program first of all, and a file with the extension .TXT magically appears in the folder where you installed the program.
Unfortunately the installation of the software relies heavily on the user having a working knowledge of running DOS programs under Windows - and, I suspect, it may not work under NT or 2000.
I find that DOS programs occasionally crash Win98, so WinME may have problems, too..
