If you are using Skype 5.2 or 5.3 for Windows and you attempt to add a contact, you may find that the Add Contacts window is blank or only partially shown.
                    Our engineers are working hard to fix this problem. In 
                      the meantime, make sure that you are using the latest 
                      version of Skype. If you’re not sure what version of 
                      Skype you are using, it’s easy to find out.
