Hi all,

I have a custom form method that issues the following UPDATE statement involving two cursors:

UPDATE c_Store SET ;
		c_Store.nMin = c_MinMax.nMin ;
	FROM c_MinMax WITH (Buffering = .t.) ;
	WHERE c_Store.cGroup = c_MinMax.cGroup ;
		AND c_Store.lLock = .f. ;
		AND c_MinMax.nMin > -1

This has been working fine, but today in testing it started causing this on a pretty regular basis:

Fatal error: Exception code=C0000005 @ 10/25/2005 16:06:41. Error log file: c:\Program Files\Common Files\Microsoft Shared\VFP\vfp9rerr.log

	Called from -  almain line 78  {N:\TestingSQL\AL\programs\almain.prg n:\testingsql\al\al034.exe}

I don't see anything wrong with the query, but that's the line that keeps causing the problems. How do I even start to debug this?

TIA,
Chad
