Hi guys im not sure if this should be in here or the computer software forum.
Anyway i have a bit of javascript on my website that opens up a pop up calander then on there you click on a date and it puts that date back into a text box on the original page.

This works fine for all but 1 person, they can open up the popup window ok, but when the click on one of the dates it doesnt do anything. Javascript was obvousally working in the first place as the popup window opened.
They had the problem in IE6 and still have it now they have upgraded to IE7.

I have been changing nealry all of my internet settings to try and reproduce this problem but i have had no joy, i have checked the plug ins the user has loaded on their machine and nothing there seems to be a problem.

Does anyone have any ideas of a setting which would cause this problem
