webbrowser control link.attacheventhandler memory issue

Hi,

Just can't figure out a solution for this one.

If you run a webbrowser control and

Dim link As HtmlElement
Dim links As HtmlElementCollection = WebBrowser1.Document.Links
For Each link In links
link.AttachEventHandler("onclick", AddressOf LinkClicked)
Next

This is in the documentcompleted event (where it says to), as you browse, memory usage just grows, and grows, and grows. Before you know if you have 500Mb+. Memory is released upon closing the app.

The linkclicked event is just

LastCLickedLink = link.GetAttribute("href")

None of the code examples I've seen using attacheventhandler seem to do anything about detaching, but I have tried cycling through detacheventhandler in the link clicked event as well. If I comment out the link.attachevenhandler line, the memory usage does not grow. If I look at the instances in use, there will be 1000's of 'eventhander click' still there.

I've tried various garbage collection.

Anyone any ideas?

Thanks.
