Windows 2003 SP1 and Skype

SkypeerrorI have just upgraded all of my servers and everything seems to be working fine except for skype.  When I click on the Contacts Tab the contact list is not reliably displayed.  If I close skype and then open it again then it is displayed once,  but from then on the tab changes to show focus,  but the actual contact list area continues to show the content of the previous tab (whatever that was).  In the screen shot I have attached you can see that contacts tab has focus, but the start screen is displayed.
