Magento connect stuck while installing

I am facing this problem while installing extensions, themes basically anything from magento connect. When I enter the extension key and click install It just gets stuck and even when it says done and I try and go back on admin page it says "T开发者_如何学编程here are PEAR processes running. If you will close the window or navigate away from the page, installation will be interrupted. " Has anyone faced this problem. I am working on ubuntu 9.1 and having magento 1.4. Any help would be highly appreciated.

Cheers

If you are working on the same computer and access your instalation via localhost (or 127.0.0.1) it can lead to problems. You should edit your hosts file and add same fake address such as www.localhost.com 127.0.0.1

I believe this is because most browsers don't store cookies for localhost and I have had problems with magento because of this in the past.
