I want to write an application which broadcasts a windows message to the
system.

I tried SendMessage( HWND_BROADCAST, Msg, 0, 0 ) with different values for
Msg.

I found out that for Msg < 0x400 (WM_USER) everything works, but if i tried
Msg in the range from 0x400 to 0xc000 nothing happened.

Has someone an idea ?
