Problem in calling javascript from flash

Hi all,

we are currently working with a tv site (flash) in which we have included 3 buttons , mini , standard and fullscreen.Mini will resize the browser window into a smaller size , while standard will resize it to the maximum available width and height.The fullscreen will play the video in fullscreen which is a new flash 9 feature.
The mini and standard buttons actually invokes a javascript function which resides in the flash container html page.The javascript code contains the satement window.Resizeto .The problem we are facing is that the functionality seems to behave inconsistently in IE.In IE 6 ,all the 3 buttons works perfectly.But once we touch the scrollbar , then the mini and standard wont work , it shows a javascript “access denied error”.This error does not appear when the wmode in flash object tag is made transparent.But if wmode is made transparent , fullscreen wont work.This is given in adobes website.
There is no problem in mozilla firefox .In IE7 we have the same problem as in IE6, apart from this mini and standard does not work at ALL when multiple tabs are open.
I would like to know if thr is any way we could overide the javascript error and why does the error not appear when wmode is made is transparent ?
