--- Comment #3 from Vitaliy Margolen vitaliy@kievinfo.com 2008-06-03 22:31:11 --- Please remove ~/.wine directory and run 'wine iexplire <address>' where <address> is the url you are having problems with. Don't forget to mention it here. The above command will ask to install wine_gecko where you should select "install".
