MSN messnger 7.0

[MonkeyWrench4000]

Hey. If anyone has MSN Messenger 7, maybe they can help me out. When I use the Pack option, to have a custom theme, it makes my message box much bigger then the default. Once I use any pack, my message box is permedently large, and very anoying, does anyone know how to get my message boxes back to default size?
