Hello,

Does anyone know why all displays (including the cscript window) are 
garbled/broken on the Windows 7 secure desktop with wpkg-client 1.3.14?

(Curiously it seems to look better with wpkg-client 1.3.13)

Tested on Windows 7 VMs and real hardware, 32 and 64 bit:

* Install WPKG-Client
* let it run with "Show UI"
* WPKG runs on the secure desktop
* if you switch to the secure desktop (Click "Show interactive services 
icon") - All Windows are drawn incomplete or only as black rectangles. 
-> This prevents "easy debug" (removing the /qn from the msiexec and 
looking at the output). And it's a problem with stupid installers showing 
UI although they were invoked as "quiet".


Best Regards
        Heiko
