[ubuntu] Skype: black cursor, not system cursor - Is this normal?

view story

http://ubuntuforums.org – Just installed Skype via terminal on a fresh install of Ubuntu 12.04.1. After starting Skype, I noticed that the mouse cursor changes to black when I hover over Skype's app window. Is this normal? Somehow I wonder if something went wrong while installing this. In terminal I observed a lot of i386 stuff being installed. And I wondered, because I run 64-bit. Maybe Skype installed the wrong 32-bit version instead of 64-bit? By the way, how can I find out if the Skype I run is 32-bit or 64-bit? In 'About' it says nothing about this. (Hardware)
