I'm sorry if everyone has seen this before, but I'm not sure that it
made it to the net.

----

I'm trying to write a talk-like utility and I'm having some problems
with Athena Widgets.  I have an application that opens a display on
the local host and the remote workstation(s).  It creates a text and
label widget for each talker.  

When I try to realize the widgets I get a BadCursor error from
X_Create_Window.  This problem manifests itself when I talk between
two machines running different window managers (awm and uwm).  It
works OK when I talk on the same machine (not very useful).  I guess a
window of one of the widgets is inheriting a cursor that doesn't
exist, but I'm not sure what to do about it.

Here's a skeleton:

- set up:
   XtToolkitInitialize
   XtCreateApplicationContext

- Create displays (and maintain a list) for each talker with:
    talker[i].display = XtOpenDisplay  /*with no special args*/

- Create a top-level widget on each display 
    talker[i].main_wid = XtAppCreateShell(unique_name,"Talk",
		     applicationShellWidgetClass,
                     talker[i].display,args,n)
    /* arg list is empty */

- Create widgets (this works ok)
    create a managed form widget under the main widget
    create text and label widgets under the form widget

- Realize widgets (this bombs)
   XtRealizeWidget(talker[i].main_wid);


Here's the error:
X Protocol error:  BadCursor, invalid Cursor parameter
  Major opcode of failed request:  1 (X_CreateWindow)
  Minor opcode of failed request:  24
  Resource id in failed request:  0x500007
  Serial number of failed request:  60
  Current serial number in output stream:  70


I also tried using a topLevelShellWidget, but to no avail.  Am I
missing something blatant, or is this a common problem of neophite
X programmers.

Any help would be greatly appreciated,
Ted
