Blocks that are troublesome by AJAXBrowser Info Environment
See also http://www.concrete5.org/marketplace/addons/blocks-by-ajax/forums/b... for notes on blocks that are fully compatible and http://www.concrete5.org/marketplace/addons/blocks-by-ajax/forums/t... for how to quickly test if a block will be AJAX loadable.
This may be solvable by changing the block controller and the script loading.
This appears to be a confusion with the way the C5 dispatcher validates the token associated with block actions.
I anticipate that some other blocks that submit a form back to the block controller may have the same restrictions when used with Blocks by AJAX and will consequently need to be AJAX loaded from a stack.
