first of all open the url please. and you'll face the div box on right-top edge. on IE, the line on top of image meet the border-right of div box. but on mozilla, it doesn't fit to meet. now the box has 12pt of right property. but even with right:0pt or 0px or whatever, you cannot move border-right to meet the tip of top line. left and top property appears - meet well.
->Layout, although I don't understand the bug report. It might help to more clearly state expected results and actual results.
Reporter, Could you provide additional information as requested ? (Expected /Actual Results)
The hostname does not resolve, so I cannot test this bug.... Reporter, any chance of attaching a testcase?
Marking this bug invalid since there hasn't been any response from reporter in over 3 months.
