frame placement

[Madhu]

A long running emacs (Xt toolkit) has now taken to positioning new
frames at 0x0 regardless of what the windowmanager wants.
xprop on the new frames show

``
WM_NORMAL_HINTS(WM_SIZE_HINTS):
                user specified location: 0, 0
                user specified size: 838 by 750
``

I'm wondering how this got set. there is nothing in the *-frame-list
which is doing this, xrdb -query -all is blank I can't see anything in
via x-get-resource, I can create fresh frames with user-position
parameters but I want the default to go back to window manager
placement (like it does in a fresh emacs)

Any clues would help.
