I'm getting an unhandled exception using the sample C# application and in our application.

Here are the steps:

1. Run the SyntaxEditor C# Sample Editor Application.
2. Clear out all the text by highlighting it all and pressing delete (cursor now in upper left - on line 1).
3. Between the number 1 and the cursor, just right of the yellow, left-click the mouse.
4. Status bar shows Ln 1 - Col 2 - Ch 2 - EndOfDocuementToken.
5. Start typing.

The following exception above is thrown:

Unhandled Exception: System.ArgumentException: The offset '0' added to the length '1' must be less than or equal to the count of characters in the document.
