>I have an application that runs fine from the VFP command prompt. This is an unattended data entry system in which a main form calls a form which calls other forms . . . until all data is entered. I built a .EXE with no apparent errors. When I run the EXE, the main form loads and displays fine. However, when I press a command button to load the next form, the application unloads and exits back to Windows. CONFIG.FPW simply has catman=off & mvcount=500.
