Opened DWG file closes the app instead of the DWG

[Syslogs]

Dim oleCollection As New ArrayList

If oleCollection.Count > 0 Then

            For Each OleDWGopen As String In oleCollection
                Dim dwgOpen As Document = DocumentManager.Open(OleDWGopen, False)
            Next
End If

I have code that opens a selected group of DWG files, binds any xrefs, searches for OLE objects and stores them in the oleCollection arraylist and then closes the drawings.  After all of the drawings are closed I reopen all of the DWG files in the arraylist and tell the end user to break the OLE links.  This part all works fine but when the end user closes the DWG it closes the whole AutoCAD application instead of just the drawing.  Any ideas why this would happen would be appreciated.  Thanks

My "Wild Guess" is there is something in the database that is corrupting the file and AutoCAD is crashing as a result. If you can widdle your code down to something that reproduced the issue, it would be easier to tell why.

I narrowed it down some.  The _olelinks command doesn't seem to work for us anymore.  I have tried in on AutoCAD MEP 2011 on Windows XP, 32 bit and Windows 7, 64 bit and both have the same result.

Thanks.
