Hello List,

I wrote an application that changes a users screen when they logon.  The app
uses this API to refresh the screen :

SystemParametersInfo(SPI_SETDESKWALLPAPER,0,Nil,SPIF_SENDWININICHANGE);

This has worked for more than 4 years, but a recent XP service pack has
stopped it.
The wallpaper is changed, but the user has to press the F5 key to have it
displayed.

My querys are:
a) Why has it stopped working?
b) What API should I use to get what I want?
c) Would it be possible to emulate the F5 keypress?

Thanks in advance - Chris
