Error on ScrollIntoView

[Tareq]

We use 3.3 of CKEDITOR. We face problem in the ScrollintoView function. After digging in the function's code let see the values of the local variables

offset= 0 ;
CurrentScroll =114;
winHeight = 680;

But this code block is generating error:

if ( offset > currentScroll || offset < (currentScroll - winHeight))
    win.$.scrollTo( 0, offset ); 

I solve the error by new code:

if ( offset > currentScroll || offset < (currentScroll - winHeight) || offset == 0 ) 
    win.$.scrollTo( 0, offset );
}}}}
