ot- viewing format

this is how I am now viewing OH - what is wrong? 

large blue banner across the top of page - small box to the right with 3 lines

not able to do search or view correctly. 

url does not include .m so I don't think I am in mobile mode.

can anyone help

It looks that way when you use Internet Explorer as your browser.  You can click on the 3 bars to get the Search.  I personally prefer using Firefox as my browser as I never have issues with OH with FF.
