I've noticed that in search window if you don't write something on the first box (Skype name, full name or e-mail address) the Search button doesn't get activated. So you need to write something on that box and then the Search button is activated, if you remove the text that you put on that box the Search button is maintain activated.

Thanks!

Whoops, sorry about that. Fixed for next release.

No problem. Thanks to all linux dev team
