I'm having a problem using the following:

  XSelectInput(display,root,ButtonPressMask);

The root has been found correctly, but because of a conflict with
the window manager, I get the following error

  X Error:  BadAccess
    Request Major code 2 ()
    Request Minor code 0
    ResourceID 0x8006c
    Error Serial #118
    Current Serial #118

This occurs using the following window managers olwm,olvwm,twm
but not tvtwm where it works as I want.
I there a 'proper' way to over-ride the window manager's control of the root
window periodically, so that I can receive the ButtonPress Event?
(This is under X11R4 with server Xnews)
