- Since discovering more about my problem I have modified my question
A single user is complaining that (on XP and using IE6) they're not able to follow any links around my site. The behaviour they're seeing is clicking a link shows a blank page, but doesn't change the url in the address bar of the browser. Pressing refresh at this point then displays the page correctly with the correct URL in the address bar.
All anchors are correct, and as well as testing the site in all our favourite browsers I have also tested the site myself on XP using IE6 and have no problems.
Has anyone any thoughts on what could be causing this? Perhaps it could be the fact they're within a company network for example? -- I don't see how that could cause a problem, but I am so far coming up empty.
I'm using XHTML & PHP. Headers are being received correctly. I've also ensured full PHP error reporting is on and there are no errors.
