Link borders appearing in standard blue in IE

hi guys,

im making a gallery using light-boxes and javascript.

in firefox, the borders around each linked image appear in grey in accordance with the stylesheet.

however in IE, the borders appear in the classic, un-styled blue.

if anyone has any thoughts as to why this might be happening, then please let me know.

many thanks and all the best,

mark
