I have an engineer at the company I work for who is having a problem with Cygwin. I have removed and re-installed it and so has he, and it will still not start. When you click the Cygwin executable that runs the bask.bat it opens a window for about 1 second and then instantly dissapears. Could this be a problem with other software he has installed that could interact with it? Or is this a system file problem?
