I have users running applications on our network from a VFP executable. In the directory where the .exe is stored, there are also the following files: msvcr70.dll, vfp7r.dll and vfp7renu.dll The application that the users are running has an error handler. Every once in a while, an application will bomb on a user and create a vfp7Rerr.log file instead of running my error handler. This happened today and when it happened it locked up several PC's on the network running VFP apps. I am trying to figure out if this is a software issue, or a network issue. If anyone has any theories, or explanations as to why this might be happening, I would love to hear it. Thanks!
