--- Comment #9 from Hin-Tak Leung htl10@users.sourceforge.net --- Argh, I am starting to remember - initially, all I knew was that for my purpose, it only works with the dotnet2 + ie8 combo - not with dotnet2 + ie7, nor dotnet2 + ie6 ( the last one is probably absurd, since dotnet2's system.windows.Forms.WebBrowser itself requires ie7 or something that pretends to be it) . I had a clean wineprefix for all of them, stock wine (i.e. wine-mono), dotnet2 plain, dotnet2 + ie6, + ie7, + ie8.
Then I worked out that it is because wine-gecko won't do xml + xslt on-the-fly transform (but it would open html's, just not xml + xslt), and I think somehow that was also the case for the dotnet2 + ie7 combo. So I think I need to file a bug against wine-gecko :-)...
