|I know you said right click was disbabled, maybe tap f8 on startup and then choose safe mode. Once in safe mode open IE8 and then follow the instructions below....it may work and is worth a try....|
right click on a bare spot on the above taskbar in IE8 and then click on menu bar.
That will put your menu up and then you can reset IE8...no need to uninstall it.
Some HELP in posting on Computing.net plus free progs and instructions Cheers
