UAP - CreateProcess() -> ERROR_ELEVATION_REQUIRED 740

I dicovered a strange behavior of the CreateProcess() implementation under
Vista Beta 2. I tried to run a Process with
requestedExecutionLevel="requireAdministrator" from within a process with
level="asInvoker".

What I did expect is an Admin-Credential Box on standard users accounts
(thats the case) and a an admin confirmation box on admin accounts (thats
not the case). In the last case the execution fails with GetLastError()==740
which is: "The requested operation requires elevation". It's the same error
which would occur if the user would press a "No". So what is the initiator
of error 740? If I'm using the function ShellExecute() instead of
CreateProcess the call leads to the expected confirmation box.

Next one: If the parent process execution level is "asInvoker", a system
message states compatibility problems and taken settings. The next time, I
run the application, the error 740 is disappeared. If the parent process
execution level is not given per manifest <requestedPrivileges> the
described error 740 is permanent.

note: both applications are standard VS6.0 MFC-applications.
I did not change the standard lua settings :
User Account Control: Behavior of the elevation prompt for
administrators Prompt for consent
User Account Control: Behavior of the elevation prompt for standard
users Prompt for credentials

Hello, this is Just a Friendly Reminder: Builds 5308 CTP and 5342 are not
beta 2. They are Interim Builds and are not to be considered Official Beta
Quality. Beta 2 has been Delayed until Winds day, May 24th, 2006 according
to Paul (you know who) from http://www.winsupersite.com.
 
But that date isn't accurate and more than likely wrong. Paul Thurrott
doesn't work for Microsoft, never has and will unlikely never will. Think of
all the times where Paul has got a date wrong...

Too many times for me to remember.
