We've made several improvements in how applications appear in the Flip3D view and in thumbnails in builds later than the one you are using, and we are still working on it. By the time the OS is released your application should display correctly -- assuming we have the same understanding of what "correctly" means, of course. There are certain design choices that are deliberate (e.g., tool windows are intentionally excluded from thumbnails and Flip3D). If you can give us more information about your popups (like window/class styles and whether they are owned by other top-level windows) then I may be able to tell you whether you should expect them to display in the thumbnails in later builds.
There may also be some tough cases we can't get quite right because some apps do some funny things with their windows that look great when they are all overlapped on the desktop but not when they have their "occluded" areas shown or their window structures revealed by a 3D view. We do no plan to provide a means for an app to create a custom alternative thumbnail representation, but we will provide an API to opt out of the normal thumbnail image altogether, which will then be replaced by an iconic representation. Since that leads to a reduced user experience, we do not recommend this method except for the most extreme cases where the app can't be updated to display well in all views.
Leonardo, thanks for the reply. Upon further testing, in our case it appears to be all popup windows that dont display. A good test would be to install an Adobe CS2 application like Illustrator on Vista and bring up a few of the floating palettes. They are popup windows and do not display in the thumbnails. Our future apps follow a similar UI design so we would like to know if our apps in development will have the same problem.
I look forward to your response.

Hi Leonardo,
Since I have to solve our company product to display movie in "Task Thumbnail", I have some questions to ask you.
We can not got playback movie in "Taskbar Thumbnail" when the APP is minimized.
But it works fine, when Window is shown.
Does anything or any event I need to handle?
P.S. I have tried Flip3D, our APP works well when playback movie in Flip3D.

The thumbnails are only live when the window they represent is in the restored or maximized state. If the window is minimized then it loses its visual representation, and the thumbnails show the last image of the window as it was drawn right before it was minimized. This is why your app doesn't update while minimized.
Hi,
I noticed that Windows Media Player shows the thumbnail updating (shows video playing) when it is minimized. How does WMP do it?
