Flash AS3 电影动画（和事件）嵌入到 PowerPoint 2007 中时冻结
我正在为学校开发一款产品，其中包括 Flash 动画（用 AS3 编写的 swf 文件），用于插入/嵌入到 PowerPoint 幻灯片中。除了一个问题之外，这一切都在工作：当插入/嵌入到 PowerPoint 2007 幻灯片中时，当您离开并返回包含它们的 PowerPoint 幻灯片时，我的 Flash 影片（有时）会冻结。 PowerPoint 2010 似乎不会出现此问题，但我的大多数客户都使用 PP2007，因此这没有多大帮助。我需要帮助找到针对 Flash Player 和/或 PowerPoint 中明显错误的解决方法。
通过实验，我发现当您显示包含 Flash 影片的 PP2007 幻灯片时，转到下一张幻灯片，然后返回（有时）与时间相关的事件（ENTER_FRAME、TIMER< /code> 等）已停止由 Flash Player 分派至 AS3 代码，从而冻结动画。其他事件（例如 MOUSE_MOVE、KEY_DOWN 等）以随机突发方式分派到 AS3。
我创建了一个小型 Flash 程序和 PowerPoint 幻灯片来演示该问题，并将它们放在网上：
www.eye2eyesoft01.co.uk/FlashInPowerPointProb/ExampleInclusionTestFlash.pptx（要尝试的 PowerPoint 幻灯片）和 www.eye2eyesoft01.co.uk/FlashInPowerPointProb/EventShowTest.fla（来源PowerPoint 中的 Flash 电影）
我正在寻找的是一种解决方法 - 当用户单击按钮时我可以运行一些 AS3 代码（如上面的“实验”按钮） demo），在电影重新出现在 PowerPoint 中并卡住后重新启动正常的事件调度。以前有人解决过这个问题吗？
显示问题的版本：W7-64 位上的 Flash Player 11.1.102.55（最新于 2012 年 1 月 24 日）和 PowerPoint 2007，但在另一台 W7-64 位 PC 上的 Flash Player 10.0.22.87 和 PowerPoint 2010 上显示没有问题。 AS3用Flash Pro CS5.5编译。显示问题的代码很小（请参阅 fla 源文件） - 问题显然是 Flash Player 和 PowerPoint 之间的交互 - 因此使用 Flash Builder 不太可能产生任何影响。
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.
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 (ENTER_FRAME, TIMER etc) have stopped being dispatched to AS3 code by Flash Player, freezing animations. Other Events such as MOUSE_MOVE, KEY_DOWN etc are dispatched to AS3 in random bursts.
I have created a small flash program and PowerPoint slideshow to demonstrate the problem and put them on the web at:
www.eye2eyesoft01.co.uk/FlashInPowerPointProb/ExampleIncludingTestFlash.pptx (the PowerPoint slideshow to try) and
www.eye2eyesoft01.co.uk/FlashInPowerPointProb/EventShowTest.fla (the source of the Flash Movie in the PowerPoint)
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?
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.
