Today I would like to talk about window message queue. Many developers for Microsoft windows familiar with this subject. There are many books about this subject and honestly, I was under impression that each window has own message queue. I even asked many developers around me and most developers were telling the same story. Some believe that there is one message queue for process and some even believe that there is one queue for whole session.

This was biggest feature I missed in new Skype.

And finally, Microsoft added this feature back. In fact, they added it some time ago.
