Hi David,

I have been looking into this problem.  Here is what I found.  I am running a 
simple DND test that comes with qt (examples/dragdrop).  Running kwin, it 
does not work on the second head with xinerama enabled.  Note that xinerama 
is only enabled for XFree86 and not for kwin.  I disabled all code in kwin 
(and kdelibs) that has xinerama support.  But running under twm, it works 
fine.  Digging deeper, it led me to the piece of code in qt.  The code is in 
src/kernel/qdnd_x11.cpp.  On line 1093, we have

    if ( !XTranslateCoordinates( qt_xdisplay(), qt_xrootwin(), qt_xrootwin(),
                                 globalPos.x(), globalPos.y(),
                                 &lx, &ly, &target) ) {

Now, this function returns a valid target under twm and 0 under kwin, when I 
drag on to the second head.  

What I cannot understand is why a Xlib code should depend on what window 
manager is running?  I know very little about Xlib.  So, I was wondering if 
you could help me with this?

Thanks,
Balaji
