I am trying to set the cursor for a popup widget using the XtNcursor
resource, and understand that all the children of this popup will
inherit this cursor by default. I have the following hierarchy in
my application:
           		-->Command
           	       |
               Popup--->Form---->Label1
           	       |
           		-->Label2
Defining XtNcursor for Popup or Form doesn't work. Defining XtNcursor
explicitly for Command, Label1, Label2 works. I can never display
the new cursor in the form widget even if I declare explicitly. 

Below is a small test program which exhibits the problem. The hierarchy
for the test program is:
               Top->Command->Popup->Label
The label widget does not get the new cursor.

Any help will be appreciated. Please post or email.
Thanks in advance,
