Custom Animation - PowerPoint viewer issues

[ppqa]

I am facing issues while using custom animations for Power Point 2007 or 2010. I have an application which uses third party controls and PowerPoint viewer. When i have any custom animation having motion Paths, and i try to view it in slide show the animation does not follow correct paths.



If i open the same file in PowerPoint application it works fine but it does not work fine when integrated in the application. The same file works fine in 2003 Viewer.

Please let me know why this happens with 2007 only and if there is any possible fix
