In an application I am trying to develop, requires a pointer grab through a
portion of it. While XGrabPointer works when the display is the same as the
host, it does not work if I run it with an x terminal as the display.

I am using:

status = XGrabPointer(dsp, w, True, KeyPressMask | ButtonPressMask,
		      GrabModeAsync, GrabModeAsync, None, mycursor,
		      CurrentTime);

Now:
	if app runs on panterra & displays on panterra:0 this works.
	if app runs on panterra & displays on gremlin:0 it exits with:

X Error:  BadValue
  Request Major code 26 ()
  Request Minor code 0
  ResourceID 0x5
  Error Serial #53
  Current Serial #53

(systems: panterra - SPARCstation 1+, gremlin - Sun3/50 running XKernel
 all systems running X11R4 & SunOS 4.1)

In a related aside, is it possible to use XListHosts(), XRemoveHosts() and
XAddHosts() in a similar fashion?

Any and all suggestions appreciated.

Many thanks in advance.
