When I apply the corner plugin to an element on the page, the layout is affected when I hover over a link with padding. This only seems to occur in Internet Explorer (IE 6 and 7), and I am unable to find out the cause.
To replicate, go to http://www.nelctp.nhs.uk Resize the browser window (making it bigger illustrates the problem better), the boxes in the middle should move (to stay in the centre), but they don't. Then mouse over one of the links on the right. The right box moves to the correct position when this happens. I know it is the corner plugin, as a test without it applied works: http://www.nelctp.nhs.uk/?nocorner
