The reason for the appearance of the DOS window is that commands like "dir" can not be run without a console. "dir" is not a reference to some program called "dir.exe", but is a reference to a shell command which only makes sense when executed inside 'cmd.exe' (NT's command shell...i.e. the window you are seeing) or something closely equivalent. If what you're looking for is a file listing in Mathematica, then I suggest you look up the appropriate Mathematica file commands instead (see, for example, the Mathematica function, FileNames[]). There is a legitimate complaint, however, although your example doesn't get at it. Sometimes, people want to execute windowed programs (not shell commands or console programs) using the Run[] command. However, this too pops up a console window. There is no particular reason for it to do so. It's not harmful, but it can be distracting. In a future release, Mathematica will launch shell commands in console windows, and windowed programs with no console window. However, I don't believe this change made it into version 4.
