Vista - windows contact immediately closes "menu items" when clicked

Hi,

I am having trouble when I try and use my Windows Contacts in Vista.

Basically what happens is that I can open Windows Contacts, and see my
contact etc..but when I click on a menu item such as "new contact", I can see
the window open, but then it immediately minimizes, then looks as though it
drops to the bottom of the screen (when it is really closing or hiding
somewhere).

My laptop came with Vista and this is not an upgrade if that matters.
Can someone please help me understand what I need to do to get this working
properly.

Thank you.

Carolyn
