[flexcoders] Loading several swf on the same html page cause runtime error

[garfild190]

Hi,
I have an application that enable the user to load Flex reports on a page.
Each swf is wrraped inside a frame.
If the user loads 20 swf or more, while scrolling down, he gets runtime error 
or black area instead of the report.
It all happen on IE.
Please advise why this might happen.

Thanks

Jo
