IE 8 BUGS !!

I was using IE6 since long.. then i thought of upgrading IE and installed IE8 beta 1. The browser by default had no address bar or menu bar being shown into it, but by clicking “Emulate IE7” you can use it much like IE7- in my case the “IE7 emulate” button was also grayed.. So finally i resolved to use IE7. Hence Uninstalled IE8-restart-IE7 install – restart.. bt the new installed browser also did not have any address bar or menu bar…!! So finally rolled back to IE6..which by luck has the add. bar and menu bar. I guess this is a registry entry problem, and tried solving..-all in vein. THIS IS SURELY A BUG IN IE8 !! Please help me out.. Thanks a ton!!
