What programs are you running and when do you get them?

It is generally due to a race condition between X and ratpoison. For instance, 
when a window is destroyed ratpoison gets a DestroyNotify event. By the time 
ratpoison gets it the window could be long gone on the server but rp thinks it 
still exists. In some cases rp will try to save the mouse position or restore 
the color palette for the window that is now longer there. This triggers an 
error. In earlier versions ratpoison would quit with this error. It now 
politely notifies you. Although its not fatal, these error messages indicate 
that rp is doing something incorrectly. In many cases WMs ignore bad windows 
(take a look at the 9wm source) which is what rp should do once I've made 
certain rp is performing correctly.
