Line 11 should be

'Windows 7' => '(Windows NT 6.1)',

The windows me detection is off a bit.

The fix below should do the trick

'windows-me' => '(Windows 98)|(Win 9x 4.90)',
'windows-98' => '(Windows 98)|(Win98)',

by cluke009 on Sunday, November 29th 2009 at 06:20 PM

Edit for the code above. This should cover all bases.

'Windows ME' => '(Windows 98)|(Win 9x 4.90)|(Windows ME)',
