>>I have converted my app to SQL Server database. So this has eliminated the corruption of the application DATA. But my app still, on occasion gets the "Invalid seek offset" error. The error happens when the application tries to access/open/load meta data which is still in the DBF format. I believe that "Invalid seek offset" is caused by some kind of PC memory corruption (be it from a buggy printer driver or some other).

>Walter,

My app is also using SQL Server and the meta data are in the executable. But still, once in a while, I get messages (from customers) of that dreaded ISO error. This is why I am thinking of changing meta to XML. I presume that your meta data is DBF, right?
