Trouble accessing Citrix Application Set running on Windows XPe as user other than Administrator.

I have an HP thin client running Windows XPe with the flash unlocked.  Citrix Program Neighborhood was pre-installed.  When I logon as the local administrator, I can setup and access an Application Set.  The administrator can select the application set, see all the appropriate published applications (Citrix farm  mix of 4.0 and 4.5), and launch any application using my personal domain credentials.  When I logon to the thin client using my personal domain credentials (having made my account a member of the local administrators group), I can setup the same Application Set in Citrix Program Neighborhood.  However when I double-click the application set, the window looses focus (like another window opened) and no applications are displayed.  I do not have dual monitors and the second display output is not enabled in the display properties.  I can launch applications from the web interface under my user credentials.  If I log back on as the local administrator, everything works correctly.
I would assume a permission issue since it works for one user and not another, but I am a local admin.  Maybe theres a registry permission issue?  This is my first and only attempt using Windows XPe so the issue may be in an incorrect configuration there as well.
