Vista - Some apps no longer saving login info...

I recently had a problem with MSN Explorer that the MS techs thought might
be caused by a corrupted user profile. They had me create a new account and
then, using the procedure from the MS KB, copy everything over to the new
account. It turns out that the MSN problem didn't have anything to do with
the account profile but by this time the new account had been created,
everything moved over and, since I didn't have room for a complete duplicate
account, the original account deleted.

All of my apps are installed for everyone on the computer to use and after
the transition everything seemed to work ok on the new account. Except --
It seems like there is always an "except" or "however" -- that I have
discovered that some things, in particular, the Stamps.com application for
example, won't save things like login passwords (it saves the user id, just
not the password), return addresses, etc. that it was saving under the
original account.

I called the Stamps.com tech support folks who, after trying a few things
that did not work, suggested that I create a new user account and try
installing the app there. Since this is where things started going wrong in
the first place I'm reticent to do that.

Does anyone know why an app might no longer be able to save login fields?
Even MSN Explorer will occasionally ask me for my Windows Live password even
though I am currently logged in and have only minimized the app.

Thanks in advance for whatever help and suggestions you might offer.
