I have noticed a problem with the interaction of Motif menus
and queued events.  My app will often be off doing database 
queries in a callback for 2 or more minutes. If I generate a 
button down event in the menu bar while outside the XEvent
calls and then iconify the shell I get the following error:
Warning:
    Name: menubar
    Class: XmRowColumn
    XtGrabKeyboard failed

X Error of failed request:  BadMatch (invalid parameter attributes)
  Major opcode of failed request:  42 (X_SetInputFocus)
  Minor opcode of failed request:  0
  Resource id in failed request:  0x1700047
  Serial number of failed request:  3845
  Current serial number in output stream:  3864

I have tested some other apps and this does not appear to happen
to them. Due to the necessity of handling async input from another
source (isis) I don't use the normal XtAppMainLoop but instead use
select to watch both the X and isis sockets.  I am wondering if there
is a connection there..
Any hints are welcome..
