i experience the same thing and dont know what is going on, too
I had the same with remote_function and radio buttons. It worked perfectly with FF but not with IE. In case of IE I had to click the mouse button and only then it updates.
I changed radio buttons to combo box and remote_function to event based observe_field and everything works just perfect in IE and FF.
All the Best! Sergey.
