I have a form that had a working dataenvironment. After a c00..5 crash I now get the following error:

Visual FoxPro 07.00.0000.9465 for Windows [Jan 4 2002 02:58:33] Product ID 55181-015-6254362-03916
CodeMine 7.0RC4
Error #1734 in Linkcde line 7
"IF ISNULL(THISFORM.oCDE)"
Property OCDE is not found.

Call Stack:
5 Formclientmanager.Cmdatamanager.Linkcde (..\..\codemine7.3\common50\cmdata.vct)
4 Formclientmanager.Cmdatamanager.Init (..\..\codemine7.3\common50\cmdata.vct)
3 Cmstatemanager.Cmformcollection.Add (..\..\codemine7.3\common50\cmstate.vct)
2 Tbrdevelopmenttoolbarcustom.Cmdtoolbuttonrun1.Doform (..\..\codemine7.3\common50\cmdevenv.vct)
1 Tbrdevelopmenttoolbarcustom.Cmdtoolbuttonrun1.Click (..\..\codemine7.3\common50\cmdevenv.vct)

I have killed and recreated the DE as both a native and CDE class without much effect (there are a few less lines in the Call Stack). Currently the stting for oCDE is .NULL., but I had not noticed the setting prior to the blowup and so far have found nothing in the docs to tell me what the setting should be. Suggestions?

TIA while I look around.
