Send Keys is not working on Internet Explorer

[Prudwi]

Am trying send keys into a text area, it says that send keys was successful in the logs. But, it is not actually sending the keys to that text area. Below is the Text area HTML info:

"<textarea name="sr_essm_info_survey_comments_2" maxlength="500" rows="10" cols="50" onfocus="this.select()">automation</textarea>"

Ran the selenium script on Selenium 2.53.1, internet explorer 11.576 and Windows.

Please help me with this issue.
