I mean set-window-point doesn't change point and the cusor remains where
it was (at the start of the buffer).

I think it may be due to the interaction between the window-manager and
Emacs.  Odd things happen when there is more than one frame. The display-buffer
problem that I posted earlier relates to make-frame where the doc says:

In my case it selects the frame even though the window manager is configured
for click to focus.

When using Edebug, I find that it can select a buffer displaying the current
code (the mode line goes dark) without selecting the frame, which seems

These problems are probably to obscure to convey over e-mail.  I will try to
debug the C code one day.
