I just came across this bug in another thread...
Command clicking on the following links should open a new tab
http://www.google.com
(
http://www.google.com)
As you can see, the 2nd one probably won't load up google as the ) is in the link. However you should get some feedback. As it is, nothing happens at all when you click that link. In fact even normal clicking doesn't work. I'm not saying what the behaviour should be, just that as it stands, it doesn't seem quite right. (Esp. as the status bar gives feedback as if it was a valid link, even though OW is obviously doing some check on it when I click it.)
