I have been tasked with repairing a Customers two web sites that keeps locking visitor browsers. I am a pure HTML or ASP.Net developer and the sites are currently in PHP which I know nothing about. The offending sites are at www.ukaffordablegranite.com and www.agandm.co.uk if anyone can spare the time to test if either of them lock their browser. They do not affect all browsers or all versions of each browser, so if you do get chance to visit and reply to this post, please let me know the browser and version number. Any PHP savvy guys that could View Source and give me clue as to which section of the page could be causing the problem? Thanks in advance Edit: Found out the sites only crash Explorer. Just FTP'd the sites down to our local drives for further testing.
