make sure your returning *false* FROM the event handler, not just TO the 
event handler. example:

function showLayer(){
// code
return false;
}

RIGHT:
<a href="foobar.html" onClick="return showLayer('foobar');">foobar</a>

WRONG:
<a href="foobar.html" onClick="showLayer('foobar');">foobar</a>

in the second case, onClick merely evaluates to false and does not cancel 
the action. hope this helps. - Cyanide_7
