Accessing FCKeditor between frames

Hi all,

I have page with left and right frame.I have created the fckeditor in the right frame, and it gets loaded when the page loads.Now when I access the right frame FCKeditor in my left frame, I get an error saying that

--------------------------------------------------------------------------------------------------------
uncaught exception: Permission denied to set property Window.FCK_STATUS_NOTLOADED
[Break on this error] undefined

[Break on this error] if ( FCKBrowserInfo.IsGecko )

fckconfig.js (line 21)
uncaught exception: Permission denied to get property Window.FCKeditorAPI

But if I access with URL http://localhost:8080/fckeditor it works fine but, when I access the page with
http://localhost/fckeditor it gives the above error.

I sense that error is strictly due to some problem with URL access.
Can anyone please tell me the possible workaround for this.

Thanks in advance.

Mehmood
