I added the Flash Detection Kit (client side) to one of the pages on my [ASP.NET](http://ASP.NET) site. It works beautifully except for one thing, when I click the logout link (which does a postback) I get a javascript error. The link works fine on any other pages. When I debug the error, it is caused by this line:

```auto
[SIZE=2]__doPostBack('ctl00$LoginStatus1$ctl00','')[/SIZE]

```

[SIZE=2]It says “object expected”. Has anyone else run into this problem and found a solution?[/SIZE]
