Text Entry controls won't work the first time

I'm in the process of converting my Captivate projects to HTML5 and am experiencing a number of issues.  A primary issue I'm having is with text entry boxes.  In running my conversions through preview or through my LMS stage, I'm finding that I must press TAB (or ENTER), whichever is required -- multiple times (in some cases, up to 12 times!!) before my text box entry action takes affect by either moving to the next field or to the next slide. 

I cannot seem to find where a similar problem has been brought up.  I create software elearnings and TAB, ENTER, SHIFT keys are how users navigate through the screens.  That makes this a big problem for me.  By the way, I've already made sure my text boxes are at the top of my timeline. 

Has anyone else experienced this?  Can anyone tell me what I must do to modify this action for HTML5?
