I've an image that is wrapped in an anchor tag that, through jQuery, triggers an action somewhere else on the page. When I click on the image, two tiny 1px by 1px boxes show up in the upper and lower left corners of the image.

My CSS styles explicitly state no borders for images: `a,img { border: 0; }`

It also seems to only happen in Firefox 3. Anyone else had this issue?

Here's a screenshot of the left part of the image (the graphic has a white background):

It's not the background, or the border of any other element. I checked.
