How can I open IM conversations in new windows in Skype for Mac OS X?
To make multitasking a bit easier, you can now open your instant message conversations in separate windows.
To open conversations in new windows:
Sign in to Skype.
In the menu bar, click Skype > Preferences….
Then select General at the top left.
Check Open conversation in new window when I double-click it in the sidebar.
Now you can simply double-click the name of the friend you’d like to send an instant message to in the sidebar and speak to them in a separate window.
This only works if you open the conversation from your Recent list. If your friend is not listed under Recent, go to Contacts, double-click their name and it will appear there.
