>I think el_h4ckers@yahoo.com is a spoofed email address, I dont see it listed in the yahoo profiles. Do you still have the header info for the email?

>>As all of you probably know there is no reliable way to protect foxpro prg/scx code. So it did not surprise me that a few people in the past notified me that they refox my utility YRECOVER just for curiosity.
>>(YRECOVER is downloadable here and at www.foxite.com)
>>
>>I did not protect my code anyway and though I did not support their action, I paid no special attention to those people. Partially because they supplied their names and they were grateful to me for the utility and for some new knowledge they borrowed.
>>
>>But the last week I got the blank message containing attachment with my code refoxed. No explanation, no comments, nothing.
>>It is something special, I believe, and therefore I would like to share with you the sender email address:
>>
>>el_h4ckers@yahoo.com.
>>
>>He/she should not belong to our company!
