With that little information, we can't help you very well. So, if you could give us some more details, like:
- Does this occur with all scripts? Or is it just one or more scripts in specific? And if it's a specific script, could you tell us the name and version?
- What version of Windows / Windows Live Messenger / Messenger Plus! Live are you running?
- Have you got SweetIM or SmileyCentral installed? If so, please read this and check if the problem still occurs.
- Have you got any other Messenger add-ons installed, like MessengerDiscovery Live or StuffPlug?
...we may be able to help you out.
