whenever I save an e-mail from yahoo or gmail or a google map- I can t see anything in the saved file. I open the files with the notepad or with wordpad and I m able to see the text- but together with html code and an error message that says that maybe java script is disabled or turned off- but Java is enabled and turned on in the options of Internet explorer 7.
