Vaadin7 with IE

Im fairly new to Vaadin and to web developement…
I wrote a web server using Vaadin 7.64 running over tomcat 7.0xx. everythig is fine with chrome, firefox and Opera browsers. It seems that the pages are not renderd or not loaded correctly on IE. I tested on IE 9 and 11 and got the same result. I Opend root log4j loggers and it does not give me any indication to what might be wrong.
I attach screen print from firefox and from ie.
I appriciate any idea, suggestion or educated guess.
