OS: Windows XP SP2

I just upgraded from Office 2003 to Office 2007.

In Office 2003 I could send and receive animated signatures. In Office
2007, the signaures are no longer animated, and I receive them as attachments
rather than as imbedded in the email itself.

The same is true of stationery. When I receive an email the stationery is
separated from the actual message and is attached as an attachment.

Is there a setting that I need to change to correct this? I have looked and
tinkered with all I figured might affect these items, but I have not yet
stumbled upon the solution.

Any help anyone might provide will be greatly appreciated.

Thanks,

Chris
