Older skins get some JS Error in Internet Explorer 6 and 7

We get an error on the following lines (165 and 166) in the curriki and albatross skins:

<li id="xwikieditwiki"#if($editor == "wiki") class="active"#end><a href="$doc.getURL("edit", "editor=wiki&$param")" onclick="return Try.these(function() {document.forms.${formname}.action='$doc.getURL("edit", "editor=wiki&$languageparams&$param")'; document.forms.${formname}.submit(); return false;});">$msg.get("editWiki")</a></li>

error is "; expected"

and this on only in the curriki skin

<script type="text/javascript">
Event.observe(window, "load", function()

, true);
</script>

error is "object expected"

None of these errors happen in toucan. However this breaks compatibility with the past. We should find a way to make it work with older skins.
