Thanks, but Application is running within a windows frame utilizing some Java SunAwtCanvas... anything within it is not visible to me from Perl. only graphically. Found the Win32::ActAcc module, here is the Perl code I used to detect any "lasting change" over a 2 second period... It appears very handy for working with other applications...

use Strict;
use Win32::OLE;
use Win32::ActAcc;
use Win32::GuiTest qw(:ALL :SW);
 
 my @win;
 my %Wnm;
 my %VW;

 Win32::OLE->Initialize();
 while ( 1 ) {
  @win = ();
  @win = FindWindowLike(); 

  #*# report any "lost" windows:
  for $win ( @win ) { delete $Wnm{$win}; }

  if ( scalar keys %Wnm) {
    print "Lost:\n";
    my @Lost = sort keys %Wnm;
    for (@Lost) { print "$Wnm{$_}\n"; delete $Wnm{$_}; }
    print "\n";
  }

  for $win ( @win ) { dumpwin($win); }

  print "\n----\n";
  sleep(2);
 }
exit;

sub dumpwin {
  my $win = shift;
  print "Null handle\n", return unless ($win); 

  my $w_text   = $win . ' ' . GetWindowText($win); 
     $w_text  .= " class="  . GetClassName($win);
  my $w_state  = ' V=' . IsWindowVisible($win) . ' E='; 
     $w_state .= IsWindowEnabled($win); 
  $Wnm{$win}  = $w_text . ' ' . $w_state;

  my $ao = Win32::ActAcc::AccessibleObjectFromWindow($win);
  my $aatxt = '';
  $aatxt = $ao->describe() if defined $ao;
  $w_state .= ' ' . $aatxt;

  if ( exists $VW{$win} ) {  
    return if ( $VW{$win} eq $w_state );
  }
  $VW{$win} = $w_state;

  print $win,      GetWindowText($win);
  print " class=", GetClassName($win);
  print " vis=",   IsWindowVisible($win); 
  print " en=",    IsWindowEnabled($win); 
  print "\n ",$aatxt, "\n"; 
}
