well, I can reproduce another C0000005 error. here is the dump and the code that crashed it, synopsis following the code..

VFP6 caused an invalid page fault in
module MFC42.DLL at 0137:5f4012a1.

LOCAL lcRateNum

DO FORM frmOpen WITH "RateSheet" TO lcRateNum
IF (VarType(lcRateNum) == 'C')
IF (oApp.formIsOpen("frmRateSheets"))
* THIS IS THE LINE THAT CRASHES
oApp.forms["frmRateSheets"].Goto(lcRateNum)
ELSE
DO FORM frmRateSheets WITH lcRateNum
ENDIF
ENDIF

my oApp has a forms_access(), that looks up the form named "frmRateSheets". This code crashes VFP. If I do ANYTHING with teh return value, however ( ?... , x = ...) then it does not crash!!!

what a ridiculous error. A head from ass extraction is necessary in Redmond.
