By the way, what happens when you spawn a new window by selecting FILE - NEW - NEW WINDOW ?
Edit>> other suggestions:
1) close all windows except for the one that opened minimized, right click on the taskbar and pick 'tile windows horizontally'- then close IE and relaunch it
2) change your screen resolution, something may get changed in the registry, then reboot and launch IE again
3) make sure there isn't a program you don't know about starting when you start windows that might affect window sizes (i.e., run adaware)
4) in the IE6 Internet Options - Programs, click on 'Reset Web Settings'
5) Reinstall IE6
