page scrool down automatically

ok, thak you for the tip.

ckeditor is placed into a standard html page.

here's my config file:

CKEDITOR.config.startupFocus = false;
CKEDITOR.editorConfig = function( config )
{

    
   // Define changes to default configuration here. For example:
   config.language = 'it';
   // config.uiColor = '#AADC6E';
   
       // This is actually the default value.
       
       // ['Form', 'Checkbox', 'Radio', 'TextField', 'Textarea', 'Select', 'Button', 'ImageButton', 'HiddenField'],
       // ['Source','-','Save','NewPage','Preview','-','Templates'],
    config.toolbar_Full =
    [
       
        ['Cut','Copy','Paste','PasteText','PasteFromWord','-','Print'],
        ['Undo','Redo','-','Find','Replace','-','SelectAll','RemoveFormat'],
        
        '/',
        ['Bold','Italic','Underline','Strike','-','Subscript','Superscript'],
        ['NumberedList','BulletedList','-','Outdent','Indent','Blockquote'],
        ['JustifyLeft','JustifyCenter','JustifyRight','JustifyBlock'],
        ['Link','Unlink','Anchor'],
        ['Image','Flash','Table','HorizontalRule','Smiley','SpecialChar','PageBreak'],
        '/',
        ['Styles','Format','Font','FontSize'],
        ['TextColor','BGColor'],
        ['Maximize', 'ShowBlocks','-','About']
    ];
    
};

now ckeditor doesn't have focus anymore, but the page still scroll down.
it seems like ckeditor have an anchor.
this affect only firefox. On ie8 i everything is ok.

i don't why.

an update:
if i set in config.js

 CKEDITOR.editorConfig = function( config )
{
 config.startupMode = 'source';
 config.scayt_autoStartup = false;
 config.startupFocus = false;
// config.toolbarStartupExpanded = false;   
   // Define changes to default configuration here. For example:
   config.language = 'it';
   // config.uiColor = '#AADC6E';
   
       // This is actually the default value.
       
       // ['Form', 'Checkbox', 'Radio', 'TextField', 'Textarea', 'Select', 'Button', 'ImageButton', 'HiddenField'],
       // ['Source','-','Save','NewPage','Preview','-','Templates'],
    config.toolbar_Full =
    [
       
        ['Cut','Copy','Paste','PasteText','PasteFromWord','-','Print','Source'],
        ['Undo','Redo','-','Find','Replace','-','SelectAll','RemoveFormat'],
        
        '/',
        ['Bold','Italic','Underline','Strike','-','Subscript','Superscript'],
        ['NumberedList','BulletedList','-','Outdent','Indent','Blockquote'],
        ['JustifyLeft','JustifyCenter','JustifyRight','JustifyBlock'],
        ['Link','Unlink','Anchor'],
        ['Image','Flash','Table','HorizontalRule','Smiley','SpecialChar','PageBreak'],
        '/',
        ['Styles','Format','Font','FontSize'],
        ['TextColor','BGColor'],
        ['Maximize', 'ShowBlocks','-','About']
    ];
    
};

there is no scroll.

anyway if i set wysiwyg mode the issue it's still there.
