Combo only works on localhost (IE8)

Suite and Optimus Suite 5

hello
i am using dhtmlxCombo and it works fine if the address is localhost and not IP :
IE8 : localhost:8080/ProjectName (YES) IP:8080/TextEntry-Portal (NO :blush: )
IE9: localhost:8080/ProjectName (YES) IP:8080/TextEntry-Portal (YES)
FireFox: localhost:8080/ProjectName (YES) IP:8080/TextEntry-Portal (YES)
CHROME: localhost:8080/ProjectName (YES) IP:8080/TextEntry-Portal (YES)

so basically my component doesn’t work only in IE8 using IP , i guess there is some kind of security configuration that restricts this component from working properly on IE8 using IP and not localhost.
Can u help ?
