`  ==Navigation popup problems with Opera== I've encountered a number of problems with the navigation popup tool and Opera 8 for Linux: *After showing for a few seconds, the popup expands with between one and five pages of mostly Chinese characters.  I assume this is supposed to be a page preview. *The popup always has a broken image link on the right side. *The popup functionality appears to cause serious problems with clicking on ``diff`` and ``cur`` links in article history: the cursor may refuse to change from an arrow to a hand, clicking on a link may do nothing, clicking on a link may take several seconds to several minutes to register. *Displaying a page history may cause the broswer to use 100% of available CPU time.  `
