Hello folks,

refining summary and adding some explanation ;-)

People still seem to use 'winetricks ie6' recipe in attempt to fix something
but in reality making things worse.

Wine's builtin mshtml uses this IE7+ API

Source:
http://source.winehq.org/git/wine.git/blob/e61de218ee3f0924252ea690be72f01d8...

MSDN: http://msdn.microsoft.com/en-us/library/ms775098%28v=vs.85%29.aspx

IE6 provides an old version of urlmon.dll which doesn't export such API.

+module gives:
