Steve,
Your program issuing a resize request for every resize event seems to be
tickling a pathology of some sort. If you start dragging real slow, it seems to
work (at least on my machine) but then goes bonkers. Its an infinite loop,
since Pending() never fails. But my sense is that after it falls behind a
certain amount, resize events and resize requests form their own feedback loop.
It is either that or some kind of competition between the window system and the
application, as to who is processing input events, and which window retains the
focus. It is like: we are having to repaint the window so many times, the
window system isn't able to continue the drag/resize operation at speed any
more.
Feel free to contribute improvements to the C code for handling window resizes.
It tries pretty hard to do things like suppress adjacent resizes to avoid
falling behind, but maybe your explicitly resizing in the middle of that
defeats the code that is there.
Cheers,
Clint

That works, but the following version doesn't (where the user can
drag out a new window size):
procedure main()
w := open("resize", "g", "size=400,400", "resize=on")
repeat {
while Pending(w) do {
Event(w)
x := WAttrib(w, "width");
WAttrib(w, "size="||x||","||x)
}
}
close(w)
end
