I'm using the following code in Perl/Tk to keep a button hovering over another app at a certain spot in its window. ($ide is a Win32::CtrlGUI object that refers to the other app.) 
sub CheckIDE {
  my $vis = $ide->get_property('foreground') == $ide ? 1 : 0;
  my $coord = $ide->get_property('rect');
  exit unless defined $coord;
  if ($vis > $curvis) {
    $mw->deiconify;
    $mw->raise
  } elsif ($vis < $curvis) {
    $mw->withdraw
  }
  $curvis = $vis;
  my ($rgt, $top) = map {$coord->{$_}} qw/right top/;
  $rgt += $dx;
  $top += $dy;
  $mw->geometry("+$rgt+$top");
  $check = $mw->after(10, \&CheckIDE)
}

The code works as I want it to, but I can watch the program's memory allocation climb as it runs. I've isolated the apparent memory leak to the 
  my $coord = $ide->get_property('rect')

statement. It would appear that the hash referenced by $coord is never returned to the heap when this subroutine returns.

Does this analysis sound right? What can I do prevent the ever-increasing memory footprint?

Thanks,
-Phil
