Can't narrow down the cause, but we have lots of these coming though when the checkout attribute using textbox for delivery instructions is completed.
i.e.
Catalogue Request: Yes<br />Delivery Instructions: Please%20deliver%20on%20Friday%201%20March%2C%20and%20please%20knock%20door%20knocker%2C%20and%20allow%20time%20for%20me%20to%20come%20downstairs.
and xml stored like this
<Attributes><CheckoutAttribute ID="1"><CheckoutAttributeValue><Value>1</Value></CheckoutAttributeValue></CheckoutAttribute><CheckoutAttribute ID="2"><CheckoutAttributeValue><Value>Please%20deliver%20on%20Friday%201%20March%2C%20and%20please%20knock%20door%20knocker%2C%20and%20allow%20time%20for%20me%20to%20come%20downstairs.</Value></CheckoutAttributeValue></CheckoutAttribute></Attributes>
Might be users on IE, but can't be sure.
Any ideas why this might be happening and how to stop it.
Thanks
