javascript null function.

Hi there:
I would like to make a image with no HREF but with an onmouseover in it. So i code this:

..
..
function donothing() {
}
</script>
<body>
..
..
<a href="javascript:donothing()" onMouseOver="foo1('resultado');return true"><img src="foo.gif"></a>
..
..

Ok, it works fine, but when I push the image my cursor changes into the hourglass (*clock) like if I was pressing over a link image. Is there any way to avoid this annoying hourglass (*clock)? Is there any way to asociate a javascript function to an image without HREF?

Thanks in advance.

(*) My English is really bad, so I'm not sure if "hourglass" is the correct word for the wait clock of windows 95.

function donothing() { return false; }

but that of course will change it into a hand instead.

In MSIE 4 and Netscape 4 you should be able to use DHTML to swap divs and layers on mouseovers on any html element

how about
<a href="" onMouseOver="foo1('resultado');return true">
or
<a href="#" onMouseOver="foo1('resultado');return true">

without any need for a null function.

Rafistern - we have been there before - the page will reload

Sorry xabi: this was what I meant - remove the return false and put it in the onClick instead!

<a href="javascript:donothing()" onMouseOver="foo1('resultado');return true" onClick="return false;"><img src="foo.gif"></a>

mplungjam: Ok, it works now but there is still two problems:
1.- onClick doesn't work on IE3
2.- If I click on the image twice Backk button of the naivator must be pressed 3 times :(

Anyway it works

What does not work in IE3 (unless your foo1 is an image rollover)? I ran this with the expected results:
<HTML>
<SCRIPT>
function donothing() {;}
function foo1(avalue) { document.theform.thefield.value=avalue;}
</script>
<body>
<a href="javascript:donothing()" onMouseOver="foo1('resultado');return true" onClick="return false;"><img src="foo.gif"></a>
<FORM NAME="theform">
<INPUT TYPE="TEXT" NAME="thefield">
</FORM>
</body>
</HTML>

I use IE3.02, by the way and no extra back click was necessary
