Problem with Opera browser

[Hoopster81]

I have recently switched from Firefox to Opera, but I am having one problem. Opera is unable to navigate my e-mail client. My e-mail is a typical .edu e-mail client -- here is a picture



Anyways, when I click on buttons such as "Inbox," "Check Mail," etc. nothing happens. Is there some setting I need to change in the Opera browser to make it work?

Thanks
