I have been searching for an answer to this question for a very long time. I have checked the "open folders in the same window" radio button in the general tab of folder options. I have also been told to uncheck the launch as seperate processes button in the view tab of folder options.
Actually it was working fine. I did modification in folder options like, TOOLS -> folder options -> File type -> File folder -> advance -> new -> and I added cygwin and its path after this only I am facing this problem. Now I have no clue how to rectify this problem.
I am using windows XP professional, service pack 3.
