What does the onclick attribute look like? Is it onclick="f2();" or
onclick="return f2();" ? In the first case, the return value of f2 is
silently ignored by MSHTML. Note - you don't call f2() itself, you call
a script handler which itself is a function that calls f2. In other
words,

<a id="elem" onclick="f2()">...</a>

is equivalent to

<a id="elem">...</a>
<script>
elem.onclick=function(){f2();}
</script>

Note that the function assigned as a handler does not return any value,
even though f2() does.
