David,

In

http://lists.w3.org/Archives/Public/public-css-testsuite/2010Aug/0059.html

I reported these problems and proposed replacements for each of them.
They are still available:

http://www.gtalbot.org/BrowserBugsSection/css21testsuite/border-bottom-width-036.htm

http://www.gtalbot.org/BrowserBugsSection/css21testsuite/border-top-width-036.htm

http://www.gtalbot.org/BrowserBugsSection/css21testsuite/border-bottom-width-047.htm

http://www.gtalbot.org/BrowserBugsSection/css21testsuite/border-left-width-047.htm

http://www.gtalbot.org/BrowserBugsSection/css21testsuite/border-right-width-047.htm

http://www.gtalbot.org/BrowserBugsSection/css21testsuite/border-top-width-047.htm


I also reported these again in

http://lists.w3.org/Archives/Public/public-css-testsuite/2010Sep/0098.html

and then again (along with others in) in

http://lists.w3.org/Archives/Public/public-css-testsuite/2010Sep/0161.html

-------------------

Missing in your list are:

http://test.csswg.org/suites/css2.1/20101001/html4/padding-top-050.htm

and

http://test.csswg.org/suites/css2.1/20101001/html4/padding-top-051.htm

You have to view these padding-top-05? in Opera 10.63.

regards, Gérard
