>I'm wondering if there exists a class that creates a toolbar that the user can customize and that give the user a quick launch of their FUP's (frequently used programs). As these FUP's are different for each user, the toolbar should be different for each user ...

THe star bar in IE4 and later versions of windows does this. Just drag an icon to it, and it lives there, next to the IE, Outlook express and whatever else icons. Makes my FUPs (Frequently Used Programs) a snap to get to.
