There are two ways how do that: 1) Set return value of "onmouseup" handler to "false" (see Test case) 2) Call method event.preventDefault() (see Test case modification) Disabling of default action is affecting behavior of other events - but they couldn't be affected (try test case in Firefox). So that after mouseup isn't triggered "mousemove" event in this case. Steps to Reproduce: 1) Open test case in Safari (WebKit) 2) Move mouse up and down over text 3) Click on some text in testcase 4) Move mouse up and down over text Actual Results: When I moved mouse, items are not highlited. Expected Results: When I moved mouse, items will be highlited.
