Every time I do anything on Skype, open up a contact for chatting, or talking, or many other actions, the dialpad pops up:

It's particularly problematic when I start chatting, because I double click a contact, start typing and instead of sending a message, I'm dialling. It only happens in one of my two computers, both running the same version of MacOSX and Skype. On the computer with the problem it happened since I installed Skype.
~/Library/Preferences/com.skype.skype.plistas well to reset that. Check if that works. You can disable the dial pad window with theCmd-2shortcut, but that won't be a permanent change, of course. – slhck Feb 3 at 14:40
