I,m running across the Invalid Page Fault that shuts the program down immediately and I'm wondering if there is a workaround. When I call form B from within form A, and then release form A from within form B, then put the focus on any other FoxPro window, this error message comes up and shuts the program down. The forms are modeless. Basically I have a login form that needs to be destoyed when the called form is intitialized. Any ideas? Any help appreciated.
