Cursor jumps between text fields

ok here's some sample code. in the HTML I have:

       <fieldset class="well the-fieldset well-odd">
            <legend class="the-legend the-legend-odd">Documentation Supplied</legend>
            <div class="row-fluid">
                <div class="well">
                    <div class="span2"><input type="hidden" name="data[Observation][lesson_plan]" id="ObservationLessonPlan_" value="0"/><input type="checkbox" name="data[Observation][lesson_plan]"  value="1" id="ObservationLessonPlan"/><label for="ObservationLessonPlan">Lesson Plan</label></div>                    <div class="span2"><input type="hidden" name="data[Observation][scheme_of_work]" id="ObservationSchemeOfWork_" value="0"/><input type="checkbox" name="data[Observation][scheme_of_work]"  value="1" id="ObservationSchemeOfWork"/><label for="ObservationSchemeOfWork">Scheme Of Work</label></div>                    <div class="span2"><input type="hidden" name="data[Observation][group_profile]" id="ObservationGroupProfile_" value="0"/><input type="checkbox" name="data[Observation][group_profile]"  value="1" id="ObservationGroupProfile"/><label for="ObservationGroupProfile">Group Profile</label></div>                    <div class="input textarea"><label for="ObservationNotes"><b>Notes:</b> (Does the LP reflect the GP? Does it match the SOW? Does it mention SfL?</label><textarea name="data[Observation][notes]" rows="2" class="input-xxlarge" cols="30" id="ObservationNotes"></textarea></div>                </div>
            </div>

            <div class="row-fluid">
                <div class="span4 well"><label for="ObservationLessonContext">Lesson Context</label><textarea name="data[Observation][lesson_context]" class="input-xlarge ckeditor" cols="30" rows="6" id="ObservationLessonContext"></textarea></div>                <div class="span4 well"><label for="ObservationLearningObjectives">learning objectives for this lesson</label><textarea name="data[Observation][learning_objectives]" class="input-xlarge ckeditor" cols="30" rows="6" id="ObservationLearningObjectives"></textarea></div>                <div class="span4 well"><label for="ObservationObjectivesMet">To what extent were the learning objectives met?</label><textarea name="data[Observation][objectives_met]" class="input-xlarge ckeditor" cols="30" rows="6" id="ObservationObjectivesMet"></textarea></div>            </div>
        </fieldset>

        <fieldset class="well the-fieldset well-even">
            <legend class="the-legend the-legend-even">Teaching Learning</legend>

            <div class="row-fluid">
                <div class="span6 well"><label for="ObservationStrengths">Strengths</label><textarea name="data[Observation][strengths]" class="span12 ckeditor" cols="30" rows="6" id="ObservationStrengths"></textarea></div>                <div class="span6 well"><label for="ObservationWeaknesses">Weaknesses</label><textarea name="data[Observation][weaknesses]" class="span12 ckeditor" cols="30" rows="6" id="ObservationWeaknesses"></textarea></div>            </div>
            <div class="well"><label for="ObservationImprovement">Ideas for Improvement</label><textarea name="data[Observation][improvement]" class="span12 ckeditor" cols="30" rows="6" id="ObservationImprovement"></textarea></div>
            <div class="row-fluid">
                <div class="span6 well"><label for="ObservationAssessmentStrengths">Assessment Strengths</label><textarea name="data[Observation][assessment_strengths]" class="span12 ckeditor" cols="30" rows="6" id="ObservationAssessmentStrengths"></textarea></div>                <div class="span6 well"><label for="ObservationAssessmentWeaknesses">Assessment Weaknesses</label><textarea name="data[Observation][assessment_weaknesses]" class="span12 ckeditor" cols="30" rows="6" id="ObservationAssessmentWeaknesses"></textarea></div>            </div>
        </fieldset>

        <fieldset class="well the-fieldset well-odd">
            <legend class="the-legend the-legend-odd">Students' views on Teaching and Learning</legend>
            <div class="row-fluid">
                <div class="span6 well"><label for="ObservationStudentPositive">Student Positive</label><textarea name="data[Observation][student_positive]" class="span12 ckeditor" cols="30" rows="6" id="ObservationStudentPositive"></textarea></div>                <div class="span6 well"><label for="ObservationStudentNegative">Student Negative</label><textarea name="data[Observation][student_negative]" class="span12 ckeditor" cols="30" rows="6" id="ObservationStudentNegative"></textarea></div>            </div>
        </fieldset>

So basically a bunch of text fields (in some cases 21 on a form) with the ckeditor class attached to them. the field are also themed with bootstrap.

Some of the users are compaining that when they type in the boxes the cursor will suddenly jump to a different box. This happens in both IE and chrome. We've tried the obivous things like disabling the laptop tracker pad.  

It's one of those really anoying problems that I havn;t been able to reproduce on my own machine.

I have finally been able to work out what seems to be cuasing this issue.

It's the scayt plugin. When scayt is enabled by defualt, and you have two text fields side by side, as scayt detects a mistake in the second field the cursor jumps to the first field.
