Text cursor issue

I have 2 pdf form documents that I created.  When these documents are opened, there is focus on the first instance of a multiline text box. You can see the text cursor blinking there. I see this behavior even though I did not setFocus via javascript and the focused multiline form field is not the first field in the document. I tried setFocus via javascript open page action on the first field.  There is now focus on the first field but the multiline textbox retains the text cursor(which is now frozen- it stops blinking). Is there any way to fix this programmatically? I ultimately do not want any focus on any fields when I open the pdf document.  I tried various code but it did not work. I did manage to fix this issue by reinstalling my Acrobat Reader - even though the Acrobat Reader is the same exact version.  My colleague had the same issue with his Acrobat Reader so I am afraid customers will see this same issue.  I was using Acrobat XI Pro for development. Any help would be appreciated. Maybe it was a bug introduced with the buildup of multiple version updates in the past? Other PDF readers do not exhibit this issue.
