I accidentally balls'd something up, and Skype has begun using multiple windows e.g. when i open a call it opens the call in a window for itself, where before it would be a part of the main window where my contacts are. There's probably a simple solution to fixing the problem but i cannot figure it out.
Sounds like you've selected Compact View. Click on View > Default View to fix the problem.
