RE: ILocateCommandEvents abruptly exiting subroutine

[quote user="Darin Rodberg"]oNode.textLine(1) = txt [/quote]

Clearly we should consider that line suspect, but of what I don't know.  Try adding some trace statements to show us what's going on...

Debug.Print "TextNode has " & oNode.TextLinesCount & " lines"
Debug.Print "Current content of oNode.textLine(1) '" & oNode.textLine(1) & "'"
Debug.Print "About to replace with '" & txt & "'"
oNode.textLine(1) = txt
