i386 v6.3 MacOSX: cursor.pro not responding to mouse button events [message #54883]

I'm trying to use a direct graphics routine from the astronomy library
called curval.pro on a Mac i386 laptop. The mouse is a three-button
mouse that is functioning fine outside of IDL (i.e. left button is
primary, right button is secondary, scroll wheel is button 3, etc.).
In curval, there is no response to mouse button events.

Here's the code fragment that should update !MOUSE from the cursor.pro
built-in:

LOOP: sv_err = !MOUSE.BUTTON
!MOUSE.BUTTON = 0
cursor,x,y,2,/DEVICE,/CHANGE
cr_err = !MOUSE.BUTTON
if cr_err EQ 4 then begin
print,' '
if fileflag then free_lun,lun
return
endif

The rest of the routine prints out x and y as the mouse is moved
across the window. This works correctly but there's no way to quit out
of the loop since !MOUSE.BUTTON=4 is the exit condition. I have to
Control-C to crash curval and then retall to get back - not a very
elegant solution...

Nothing in my .Xdefaults file would seem to be messing with mouse
functionality in X-windows. The only relevant entry might be a
"*keyboardFocusPolicy: pointer" statement, but this is also in my PPC
machine version that works correctly.

Any suggestions?
Thanks,
Tom
