IE 10 does not display our menuing system without modifying "compatibility settings"

If you visit [login to view URL] you will see a blue bar of drop down menu selections at the top of most pages. This has worked well for us until IE 10 was released. In IE 10, the menus do not work unless you click on "Tools", then "Compatibility Settings", then "Display all Websites in Compatibility View". You will see this note at the top of our website pages. I am looking for options to correct this problem. I've attached a portion of our existing menuing file from "brothercake". The options could be: 1) Switch to a different 3rd party menuing program. 2) Provide a note to IE10 users to change their settings. 3) Automatically change IE10 users settings after asking their permission. 4) Something else.... In your bid, please present your suggestion on how you would fix it.
