[Forum] Reputation - javascript error

[S1OPP]

Running 4.0.0 (Gold) with the default style.

When I click the "add to user's reputation" icon I get an error in yuiloader-dom-event.js

This only seems to happen in IE8

Error message:

If I click on the icon again, it works without any problem.

I first noticed it in RC4, and was hoping it would be fixed.

Thanks in advance.
