We are getting fatal errors in our application (created in VFP7 with Service Pack 1). These are Exception Code = C0000005 or = C000001D. On clicking OK, we get another error message, "Mismatched pushjmp/popjmp.call." On clicking the OK of this one, the application just closes down.

We have not been able to determine what is causing this. It happens when the application is run on different Windows systems, and when users are in different areas of the application. Also, it doesn't happen consistently. We have noticed that many instances occur when closing out of previewing a report, but this is not always the case. We have been unable to replicate the error, but it keeps happening.

If anyone has any ideas on how to track this down and fix it, we would love to hear them.

Thanks.
