Hullo from Greg Bennett who is running under Clozure "Version 
1.11-r16810M  (LinuxX8664)"
I am using the code from  the CLIM 2.2.2 User Guide to get a window 
(*test-frame*) and its
associated pane (*test-pane*).

Now I'm trying to set the position of the pointer in that pane. Once 
I've done this, I can them
do things such draw-line from this position to another one.

As far as I can see I need to use the material in CH 15: Manipulating 
the pointer in CLIM.

So I have done this:

(setf pprt (port-pointer (port *test-pane*))) -> #<CLIM-CLX::CLX-POINTER 
(setf zpt (make-point 100 100))

Currently (pointer-position pprt) -> NIL

P283-4 suggests I should be able to do something like the following:

(pointer-set-position pprt 100 100) -> Evaluation aborted on 
telling me that pointer-set-position in undefined.

(setf (pointer-position pprt) zpt) also returns an error: no method for 
setf on pointer-position.

I poked about in the CLIM Spec to no avail, perhaps because my approach 
is a wrong one.

Thx for any and all advice and assistance.

Cheers /GB
