Exception in Chrome, FireFox, and IE : Unexpected Token

[CatOnMars]

When the iframe is being loaded, Chrome and Firefox, IE all throw exceptions: unexpected token ILLEGAL

This is happening due to using numerical ID as function name prefix.

// Register a uniquely-named load event callback for this frame.
ExternalInterface.addCallback(_frameId + "_load", handleFrameLoad);

it results in illegal javascript function name
"0_load" "1_load" "2_load" ... etc.
thus preveting loading function from execution.

Hope this could be fixed.
Thanks: )
