  1. POFlash AS3 movie animations (and Events) freeze when embedded in PowerPoint 2007
    text
    copied!<p>I am developing a product for schools including flash animations - swf files written in AS3 - for insert/embed into PowerPoint slideshows. It is all working apart from one problem: when inserted/embedded in PowerPoint 2007 slideshows my flash movies freeze (sometimes) when you leave and return to a PowerPoint slide containing them. The problem doesn't appear to show with PowerPoint 2010, but most of my customers have PP2007, so that doesn't help much. I need help finding a work-round for what is obviously a bug in Flash Player and/or PowerPoint.</p> <p>By experimenting I have found that when you show a PP2007 slide containing a flash movie, move on to the next slide and then return, (sometimes) the time-related Events (<code>ENTER_FRAME</code>, <code>TIMER</code> etc) have stopped being dispatched to AS3 code by Flash Player, freezing animations. Other Events such as <code>MOUSE_MOVE</code>, <code>KEY_DOWN</code> etc are dispatched to AS3 in random bursts.</p> <p>I have created a small flash program and PowerPoint slideshow to demonstrate the problem and put them on the web at:</p> <p><a href="http://www.eye2eyesoft01.co.uk/FlashInPowerPointProb/ExampleIncludingTestFlash.pptx" rel="nofollow">www.eye2eyesoft01.co.uk/FlashInPowerPointProb/ExampleIncludingTestFlash.pptx</a> (the PowerPoint slideshow to try) and <a href="http://www.eye2eyesoft01.co.uk/FlashInPowerPointProb/EventShowTest.fla" rel="nofollow">www.eye2eyesoft01.co.uk/FlashInPowerPointProb/EventShowTest.fla</a> (the source of the Flash Movie in the PowerPoint)</p> <p>What I am looking for is a work-round - some AS3 code I can run when a user clicks a button (like the 'Experiment' button in my above demo) that re-starts normal Event dispatching after the Movie has reappeared in PowerPoint and jammed. Has anyone solved this problem before?</p> <p>Versions showing the problem: Flash Player 11.1.102.55 (latest on 24/1/12) and PowerPoint 2007 on W7-64bit, but no problem showing on flash player 10.0.22.87 and PowerPoint 2010 on another W7-64 bit PC. AS3 compiled with Flash Pro CS5.5. The code showing the problem is tiny (see the fla source file) - the problem is obviously interaction between Flash Player and PowerPoint - so using Flash Builder instead is highly unlikely to make any difference. </p>
