Script editor is not opened when double click on component

   It is the most fundemental function for ghpython. I can not work with it.

  .I can not open script editor by double click or there is no option when I right click.

  .I can open python in rhino by entering command Edit Python Script. But I think it has nothing to do with grasshopper.

   I used to work on mac, parallels(virtual machine),windows 7. I thought the problem is caused by the virtual machine. But now I have loaded windows 10 to bootcamp . I have downloaded the latest trial version of rhino, latest version of grasshopper and gh python. The problem is still continuing.
