>>I haven't found a practical limit to the path setting. From what I've seen it looks like you're using relative paths. Naturally, if you move the application to a folder where the relative paths are no long valid, VFP isn't going to be able to resolve them. Use full paths if necessary. Note: The only time I've run into this problem is when the source isn't on the current setting.

Have you included the debug info in the application?
