<p>Hey,</p>
<p> </p>
<p>We are using BIRT 4.2.2.</p>
<p> </p>
<p>When some of our users move the mouse over any of the graphs on the BIRT reports it gives a "Microsoft Jscript runtime error" that list " 'undefined' is null or not an object". This is only happening on certain computers.</p>
<p> </p>
<p>The functionality of the graph is just to change the mouse icon to the hand icon (like it is for clicking hyperlinks), sometimes have some help/hoover text, and to allow the user to drill down to a new BIRT report.</p>
<p> </p>
<p>It's not a data issue since it works on some and not others using the same data. They are both using the same IE version (IE 8).</p>
<p> </p>
<p>This error is only appearing on BIRT reports, everything else is working correctly on the computers that are getting this issue.</p>
<p> </p>
<p>Thanks for any help or info as to what could be causing this.</p>
