If I insert a tag as follows for a flash object:

Unable to render embedded object: File (flexChart.swf) not found.

The page displays just fine with a 300x200 flash space. If I then edit the page in any way the height and width are changed to 32.

I can then edit the page again and resize and save and all is well.

Basically, any flash includes on the page have to be resized every time the page is edited.
