I use http://www.web.de for email, and their webmail has a list of emails. When I click one while pushing command, I don't get a new tab, even though the status bar says that it is going to open it in a new tab. When I open it with right-clicking and choosing "open in new tab", it works as expected. Normally, command-click opens a new tab without a problem, except on that website. Here is some code from the website: function sendpost(mid, indexid, document) { document.postform.rv_mid.value = mid; document.postform.indexid.value = indexid; document.postform.rv_js.value = "yes"; document.postform.submit(); return false; } and every link looks like this: <span class="from" id="***"><a href="/online/msg/lesen.htm?si=***&rv_mid=***&sortid=0&indexid=1" onclick="return sendpost(***,1, document);" title="misc 
<misc@mail333.com>" style="color:#000000; text-decoration:none;vertical-align:top"> misc <***> </a> </span>
The inconsistency between Cmd-Click and the context menu item is surprising. There's a high possibility that this bug may be in Safari rather than WebKit, since WebKit doesn't make any decisions about, or have any knowledge of, tabs.

r42260 Here is another repeatable example. 1. http://www.dailymail.co.uk/news/article-1168584/Blundering-Bob-police-chief-quits-terror-dossier-gaffe--walks-away-110-000-year-pension.html 2. Open link to "Print" in a new window. 3. In the new Print window, command-click on image "A section from the paper Mr Quick was carrying" (this image contains link to enlarged image). Nothing happens. 4. However, menu item "Open link in new tab" or contextual menu "Open link in new tab" works OK. AFAIK, this worked OK in previous nightly builds, but now works incorrectly in r422660.
