As you probably know, a lot of people (all people?) are having problems viewing embedded flash files

 

I made a few minor edit's on this page: Drag-and-drop and other common UI operations and afterwards the flash file was gone

In edit mode, when I right-click the flash "f" and select properties a window shows - same as the one used when you embedding images - the link is shown as "about:blank" which loooks like the link to the original file is broken -

Are they embedded in the same way as images ?

 

If there's other examples of flash files in the site (working or not) could you post the links here, thanks -  I'll add them here, that will make it much easier to check them
