While bulding PowerPoint slides I'm making use of the Height attribute of the TextBoxes on the slide to determine when it's time to start a new slide. 
    $TextBox = ${'Slide_'.$slideNumber}->Shapes->AddTextbox({Orientati
+on=>1,Left=>80,Top=>$bulletYPos,Width=>600,Height=>20,});
$TextBox->TextFrame->TextRange->{Text} = 'blah blah blah';
$TextBoxHeight = $TextBox->Height;

This works great until I start a second slide. It seems that PowerPoint needs to be told what the active slide is in order to get the correct value returned from Height. My question is how do I tell PowerPoint to activeate the latest created slide. When the presentation is being built I can watch the slides being created in PowerPoint but even as additional slides are being added, PowerPoint continues to display slide 1 until I do a page down or make a selection from the slide sorter. I recorded a macro to see what happens when a different slide is selected but the macro was blank. I tried some other things like 
${'Slide_'.$slideNumber}->ActivateWindow();

and 
${'Slide_'.$slideNumber}->ActiveWindow();

but neither worked. Thanks.
