So, maybe this isn't just something I've done wrong here. I keep 
thinking that maybe something is wrong with the dbus implementation with 
the conversion from dcop in KDE 3. It almost seems at times like KDE is 
having trouble keeping its communications going properly, so when I 
click on the desktop to launch an app, whatever handler is assigned to 
to the app launch isn't getting the notification right away. Backend 
problem maybe?

BTW, some good news. I've tested the NVIDIA 177 driver beta out here, 
and it does work with KDE4 a LOT better, you can run opengl apps while 
composting is enabled again, and performance seems much better.
