This is the only workaround I can think of to get what you want.
Go to IE tools, internet options, general. Press "use blank" to set IE's home page to "about:blank: (a blank page). Click apply, ok. Now use the "home" button to go to your new home page.
If you have active desktop, use your right mouse button to drag the icon for about:blank from your address bar to the Quicklaunch taskbar. Release and select "create shortcut". If you do not have active desktop, use your right mouse button to drag the icon from your addressbar to your desktop. Again, release and select "create shortcut".
Now when you want a new blank window, click on the shortcut you've created.
