I had the same thing. This is how I fixed it: Go into an Administrator account on your computer and select the opt directory in your cygwin directory.
Under properties-->Security your should be able to alter settings so that at least your account has "Full Control" over the "child objects". You will need to select the Advanced button and work in there. It is advisable to disable the "Inherit from parent" and use the "Replace permission on all child objects" and manually manage permissions in this folder, since all TinyOS users need to be able to read, write, and delete files here to use the tutorials and to make the Java apps. -Ben -- For some reason, the United States is the only country on Earth where accidents don't happen it's always somebody's fault, and you can sue that somebody for neglect.
