css - "Domains, protocols and ports must match" Error + Fixed div freezing in Chrome -

i'm getting error below website in chrome google adsense, , it's causing fixed position div sidebar freeze. i've looked error on here, , seem it's problem on google's part (which seems odd it's not fixed), shouldn't affect anything; see no reason why freeze fixed div.

it doesn't show in firefox or ie9, , doesn't cause problem i'm having there. error pops on browser console, sidebar stops moving.

"unsafe javascript attempt access frame url -my url- frame url -google adsense url-. domains, protocols , ports must match."

i'm not sure if i'm allowed post url demonstrate. think relevant code below ad , other sidebar.

<div id="container"> <div id="leftercontainer"> <div id="lefter">sidebar.</div></div>  <div id="contenter">content</div>  <div id="rightercontainer"> <div id="righter" class="center">google ad.</div></div> </div> 

css being. realize code may redundant, i'm beginner. work in cases except error.

#container {margin-left: auto; margin-right: auto; width:1020px;} #leftercontainer{float:left; width:129px;} #lefter {position:fixed; width:129px; margin-left:10px; margin-right:11px;} #contenter {margin-left:155px; float:left; width: 680px;} #rightercontainer {float:right; width:129px;} #righter {width:129px;} 

edit: so, above problem changed adsense code 'asynchronous' loading on google's end, turns out doesn't fix anything, leaving different error, "blocked frame origin "ad url" accessing frame origin "my url". protocols, domains, , ports must match."

but have different, more direct cause now; on page, in chrome: http://www.eh-hem.net/chat.php

the fixed position sidebar (which can see code above) freezes straight away. think it's obvious it's embedded chatbox, has code:

<embed wmode="transparent" src="http://www.xatech.com/web_gear/chat/chat.swf" quality="high" width="540" height="405" name="chat" flashvars="id=92787532" align="middle" allowscriptaccess="samedomain"  type="application/x-shockwave-flash"  pluginspage="http://xat.com/update_flash.php" />  

no errors show on javascript console, unlike ads did. quirk if resize page, sidebar moves position, not work when scroll. no 1 else same error on page?

i seem have solved issue... problem on end, regarding chrome , flash player if understand it? animated ads causing issues along chatbox... solved it, though i'm not entirely sure why stop domain/protocol/ports error: gif images in chrome loading slow and/or other problems
