I don't know. From what you told me I looked agina in the manuals and it
sounds like it should, but it doesn't.
Below is the code that I use in my small test programm. It grabs the pointer
events andthis works, as I recive all events no matter where I click, but I
played around with all settings of XSendEvent and I found no way where the
desktop resumed normal operation, as it should. My desktop runs at 1600x1200
this is why I have the if x = 1599.
