Whether this falls into this catagory I don't know, and won't know until the problem has been solved.
http://www.safariquip.co.uk appears to display very wrongly on a Mac when using either the Safari browser (Macs own) or Internet Explorer.
The cause of this problem is so far undetermined, but it is causing us some grief. We have emailed our menu company and are awaiting a response from them, however, if anyone has any ideas as to why this problem is occurring, in either browser, please post here or email me: dave@safariquip.co.uk
