>Refox always seemed to me a disguised form of blackmail e.g. I'm a hacker that will let other hackers get at your code unless you buy a copy of ReFox.

EXACTLY!!!! Actually it's a non-disguised of extortion if you ask me.

>From what I hear, there are other hacks around that will get around Refox's protections so maybe it's an obsolete product.

Yes, this is very true. Doesn't matter what level of branding you use either. Takes about 1 minute (or less) to make the mod's with a hex editor and then all your source code is exposed.

FYI - I'm working on something else that will do a better job of protecting foxpro .exe's. Soon as I get it working to my satisfaction I plan to put it in the public domain after I've put it on a few hacker sites to 'test' it to see if it works.
