We were seeing blank white or black captures often for a while,
the reason was that wonderfl is using an external web-site capture service,
and it only supports Flash Player 9!
They say that FP10 for linux is not stable sometimes, and that might be true, so I came up with an idea, "why not we generate the capture by ourselves?".
From today, ( by the way it's my birthday :-) )
I'm inserting a small piece of code into your code, for you to take captures.
Code insert is done serverside, automatically, so you don't have to do anything.
little more information here.
