--- Comment #8 from Ken Sharp imwellcushtymelike@gmail.com --- And wine iexplore works when run as root?
Please attach a console log of running "wine iexplore" without root. Always remember to include console logs.
Upgrading Wine may also yield different results. I don't understand why you're using a release candidate version.
