Seems Mozilla (0.9.7 official build, Windows, but I expect All to apply, please check and confirm) is very sensitive to Image Map Y coordinate and it ignores image map element (area in this case) if Y value of starting point is bigger than Y of ending point. For example, this element will not work in your map: <area coords="267,43,400,9" href="somewhere"> However this, makes no problems: <area coords="267,9,400,43" href="somewhere"> Setting severity to major, due to end user problems this bug leads to.
http://www.w3.org/TR/html401/struct/objects.html#adef-coords rect: left-x, top-y, right-x, bottom-y. testcase stuck in the url field. Note that nc4 and moz behave the same. if you switch to using correct coordinates, they'll both work. irc.mozilla.org#evangelism is committed to evangelizing real sites that mess up in this fassion.
''correct'' meaning Euro-centric, in this case. Four descriptions of the same rectangular area: coords="267,9,400,43" u_l | l_r coords="267,43,400,9" l_l | u_r coords="400,9,267,43" u_r | l_l coords="400,43,267,9" l_r | u_l Only upper_left | lower_right works ... just the way "we" write.
Be serious. If you prefer wasting your time on irc to debate about that instead of fixing/enchancing (name as you want) this feature, don't be surprised hearing "Mozilla sucks, because site AAA.com does not work". Let's get the point. If you can describe rectangular area by giving coords of 2 corner points, considering only one case of four as valid is illogical. Even w3c.org designed it that way, it still makes no much sense in enforcing that scheme as the only one. Life has proven that too many people don't know this exact w3c.org rule. Even Homesite, the leading Windows editor generates maps the way Mozilla can't stand. There are too many of sites around with maps like that. Let's face it: too many to defeat. So please point me to any reasonable excuse what we shall keep this "Resolved invalid" instead of fixing that problem? Don't forget to tell all Mozilla ordinary users what w3c.org is and why they should accept the fact they shall access some sites with MSIE instead of Mozilla.
Ok, following Timeless' advice, let me rephrase this bug: Some of image maps using "Rect" are not working with Mozilla, because they have coordinates of rectangle's extreme corners listed in wrong order. Macromedia's Homesite generates these from time to time, probably depending on the order in which user drawn the rectangle. The URL of this product: http://macromedia.com/software/homesite/ This could potentially influence a lot of sites, as homesite is one of most popular web editors. Reopening and reassigning to Evangelism.
I am downloading a trial to investigate this. Current version is Homesite 5, though.
I could not recreate in trial of Homesite 5. I tried multiple ways of drawing rectangular image map links. 2002030908/WinXP
After all this preaching, the problem in Mozilla was also fixed. See bug #162546.
