Desktop Authority

Problem : At logon sequence, black Background in DA10.xx


I have a problem, if a user logs on, the slogic.bat will be startet, now a user see a Picture (Splash screen style is custom) a Picture from our company.

all ok, but the backgroud is always in black, in Version 9.xx the user see  backroud from his Desktop, not a black Screen!


Why is it so, no please it not a feature :-), all older versions it was not forced with a black backgroud. 

Is it possible to config that the Background is not black, better transparent that the user see the user Desktop backgroud?
