[solved]how to release all the memory?

[FlyingBear]

in main form, when a button is clicked, it opens a new form which has a webbrowser. users can use it to browser some sites. if the user closed this form, it goes back to the main form. and they can click button to open the browser form again.

I noticed that one thing. if the browser form is opened, it uses much memory (which is normal because of the site it browses). however, after the browser form is closed, the memory is not released.

In the browser form, when it is closing, the webbrowser is disposed and dereferenced. and no other part uses much memory in the form. GC is called too. what else should I do to release all memory the browser form uses?

now, it is like once the browser form is opened once, the memory usage never goes down even the form is closed.

any suggestions?



thanks
