>Hi George,
>How is it going. For visualization I would remember it :-). In fact I would never rely on a number that's very easy to change with a few lines of assembly (it was my first copy protection years ago) :-(. Hope Jovo will use it for only something like sysinfo presentation.

Hi Cetin,

It's going OK, except that I'm dealing with an OLE automation product (not VFP) that keeps GPFing.

Part of a good copy protection scheme should be that it relies on more than one factor or item. The more complexity you add, the harder it is to figure out.
