Hi Lai,
I don't know if I get you right. You want to remove the toolbars from the Internet Explorer but still have the possibility to maximize the window to "Full Screen"?!?
Ok, might not be the correct forum for this sort of question/answer, but why don't you just remove the toolbars like you said (or Menu "View" -> "Toolbars") and use the keyboard key "F11" to maximize the window?
Hope this helps,
Robert
