>That would make sense; except. The error happens in the INIT method of the form. The INIT method in itself should be fairly fast. It is doubtful to me that during this second or a fraction of a second he opens the file and then loses connection. Also, this problem happens from time to time in exactly the same place (same INIT method). So I think most likely I (my code) is overlooking something.

And this is where the Fox Software was found compliant with Microsoft, so the purchase could proceed without hurdles. Back in FP 1.0, there was a bug when running a read statement (in many cases), which led to a similar error (1104), and in true M$ manner, even then it never said WHICH FILE is it that isn't open.
