I have migrated from VFP5 to VFP6 SP4. Does anybody know of any other commands in VFP6 that will cause the Fatal Error: Exception code=C0000005, error? I have migrated from VFP5 to VFP6 SP4 a month ago and have experienced this problem with my application. This application ran very smoothly in VFP5. This problem crops up everytime I open a form with one form opened previously. When the aforementioned forms are opened one at a time there is no problem. The form objects are loaded to an array variable in order to insure that only one instrance of a certain form is loaded at any given time. Any help is appreciated. Thanks.
