I get this effect with Opera 7.01 running on Windows XP.

Probably unrelated: The logic in Browser.php looks at a number of common 
browsers. First it looks for the "MSIE ([0-9.]+)" expression and if found 
sets the browser as MSIE. However, the agent string for Opera changes 
depending on the setting... From the log of a small apache server:

Mozilla/4.0 (compatible; MSIE 5.0; Linux 2.4.19-gentoo-r10 i686) Opera 6.11  [en]

Opera/7.0 (Windows NT 5.0; U)  [en]

While a real MSIE looks like this:

Mozilla/4.0 (compatible; MSIE 6.0; Windows NT 5.1)

It seems to me that one really should check for MSIE last, not first, in
Browser.php, to catch browsers that tries to navigate a hostile web by
looking like MSIE. The current detection routine fail on Opera when it
hides as MSIE.
