error regarding gxt chart flash

[onentwoo]

Hi
recently i am getting errors in internet explorer (9) regarding the gxt 2.x open flash chart.
unable to get value of the property "removeSWF" : object is null or undefined.

what is the problem ?
Maybe i need a clean way to handle ofc in gxt ? (i.e. somehow to clear resource).

Can you post more of an error - do you get anything else in Dev Mode? Do you get the error on any chart examples like http://www.sencha.com/examples-2/#basicchart ?
