Greetings Robert,
No security issues that I'm aware of. Both clients perform different functions. Most
notably, MSN Messenger 6 has support for display pictures, custom emoticons, has a different
interface, etc. whereas Windows Messenger supports SIP-based communications services,
Exchange IM Server, etc. Which one you use is up to you and a matter of personal choice.
However one thing to keep in mind, Windows Messenger must still be installed on Windows XP in
order for MSN Messenger to retain full functionality (Remote Assistance, Whiteboard,
Application Sharing, etc.).
