onmousemove event fires without mouse movement

Ravi · Oct 17, 2005

In IE (tested IE6 on W2k&WXP) onmousemove event appears to fire
continually
when mouse is over the document and not moving or touched at all, even
when
mouse is physically detached from the computer. Same page on Firefox
works
well (event fires only when mouse moves, not when it is static on the
document). Seems a bug, doesn't it? Anyone knows something about this
or a
solution?

Used code:
<script: JavaScript>
document.onmousemove=doit

function doit()
{alert()}
</script>

gives continuous alerts as long as mouse is over document

I would guess that the clearing of the alert box is triggering a mouse
move event.

Try:

function doit(){ window.status=new Date().getTime(); }

The other function you suggested also does the same. The status bar
gets updated with the time.

I'm surprised that worked at all:

<script type='text/javascript'>

Can you show the entire code?

I have the tried the same example at my office and my home. It behaves
as expected at home(winxphome ie sp2). at office(winXP professional ie
sp2) the counter in the status bar gets incremented with out the
mousemove.

Thanks,
Ravi

I can only conclude that your office computer is running some other process
(known to you or otherwise) that is interfering with the browsers mouse handling.
