Cannot save logon in Remote Desktop Client

The environment is XP embedded (Thin Client)

On a normal XP PC I have been saving user's name/password in their RDP file.

Now I cannot. Is XPe using a later (and more security concious version of
RDP - PROBABLY) or is this a function of XPe?

Anyway I want to save this info in RDP files regardless of security - We are
not a bank...
