Essential Objects Spell Checker Issue

The page where the Spell Checker is implemented is getting crashed if IgnoreAllCapital property of SpellChecker is set to False and any character other than an alphanumeric one like a full stop (.) is at the end of the content where spell checking is done.

Problem in detail:
• We are using a licensed version and we implement the basic Dialog based style.
• This happens only if the IgnoreAllCapital property is set to False (This is very important for us because, most of our text areas use a CSS text transform property to convert the content to capitals as soon as the user types).
• The exception thrown is System.IndexOutOfRangeException.
[IndexOutOfRangeException: Index was outside the bounds of the array.]
