Vista - AddressBar and Toolbar weirdness on IE 8 under Vista

Hi, I'm running into some major weirdness with IE 8 on a
Vista Business machine: When I use VBScript to tell IE
to hide the address bar, it displays an ugly black line which
shows the forward and back buttons in gray, the address
bar, and Live Search, but this entire line is disabled. If I
now minimize IE and then restore it, the ugly black line is
gone.

I have found that to get around this problem, I have to do
ie.toolbar = 0 before making ie visible. But I'm wondering
if anyone knows more about this issue or where it stems
from. I especially concerned about whether this is a
harbinger of some future ominous development.

Thanks,

set ie = WScript.CreateObject("InternetExplorer.Application")
ie.visible = true
ie.navigate2 "about:blank"
'ie.addressBar = false
ie.document.title = "Address Bar test"
ie.document.body.innerHTML = "Tada"
