We have several computers in our office, all running XP Pro. We use a third party, web survey application to screen questionnaires and they have to run in IE. On one particular computer, there is a functionality in the program that will not work.
In the questionnaire, one question has a series of answers that have check boxes and a none of the above box as well. Checking the none of the above box should clear out all the other answers. On this particular computer it does not.
I uninstalled Yahoo toolbar, upgraded to IE 8 and the functionality still does not work. It works on all the other computers in the office.
