In there is this notice, slightly modified to protect the website identity:
Please be advised thatHave I mentioned how much it shits me when I see notices like this?
has been designed to operate with Internet Explorer being the software of choice. Therefore to ensure maximum compatibility, please do not try and access via another Web Browser i.e. Safari or Mozilla Firefox
Maximum compatibility is when the website works on all browsers, not just that one that will support that nifty mouse over thing that you couldn't get to work anywhere else.
Perhaps "Therefore to ensure the website actually works, please do not..." would be more appropriate.
