[jQuery] link's $(this) in MSIE6

Hello,
I have a problem in MSIE 6 using such code:
a href="..." onclick="myaction(); return false;"
JS:
function myaction() {
$(this).blur(); // blurs a whole window in MSIE6!
...some animation and another actions...
}
The problem is, that in MSIE6
$(this).blur();
blurs NOT the link, but a WINDOW. What's a workaround? Or is this a
bug?
Note that it works in Firefox 2 and Opera 9.
