Can I reproduce the bug ? YES.. at any time Steps to reproduce the bug: STEP 1) click on this link http://lent.mzt.si/~davor/NavGur/index.html STEP 2) you will get on the screen a table with clickable cells STEP 3) move the mouse over the cells with the FAST movement ACTUAL result: cells change the background color when the mouse is over the the particular cell. The cell background color should be restored to the page background color when the mouse is moved from one cell to another. (please see the first GIF attachment) CORRECT result: only one cell should change the background color at a time. Previously visited cell should restore the background color to the page background color. AGAIN: only ONE(1) cell should be highlighted at any particular time. Please see the second GIF attachment. ************************************************************ HOWEVER (please please read the rest of the bug report too ************************************************************ If you move through ____ALL_____ the cells with a mouse very very slowly and wait on every cell for a second then ALL the cells will work correctly even if you start moving the mouse over them very fast In other words: if you manage to turn ON and OFF the background color of ALL cells, at least, once then ALL consecutive mouse movements (fast or slow) over the table cells will work the way they are supposed to work... ONLY one cell will be highlighted at any particular time frame the

oooops .. I've almost forgotten to say: MSIE and OPERA work OK !!

2 additional details: my browser is: Mozilla 1.1a Mozilla/5.0 (X11; U; REDHAT 6.2 Linux i686; en-US; rv:1.1a) Gecko/20020610 and second detail ( A LOT MORE IMPORTANT !!!!) As I said in my initial bug report, mozilla starts to work correctly if you turn every every cell ON/OFF at least ONCE. however... if you click on "RELOAD" button, the mozilla is confused (AGAIN) In order to make it running correctly, you have to move the mouse over the cells slowly (or fast if you go over the cells 2 times - aka turning background color on and off)

testcase shows this is not specific to tables (happens with simple <p> tag) basically: if there is a mouseOver event that changes the background color, then the first mouseOut event (whatever it is) will not work. other mouseOver events do not cause bad behavior.

confirmed with linux build 20020615 marking NEW this regressed between 2002021621 and 2002021821 also note that you can fool yourself into thinking it works if you also mouseOver the text. stay away from the text. resummarizing ==>DOM Events

marking NEW for real
