>This option is documented in the VFP books, it worked before and I don't know what to do. The GPF may also be caused by the _Screen.Visible=.t. and _Screen.Visible=.f. I use when I print (preview) reports to show the main VFP Window --> but if I remove the SCREEN=OFF from the CONFIG.FPW, everything else works.
