Thanks Vitamin. I've started testing the new Gecko and it indeed works as you said. One minor thing though: it's not the latest. Try this: Code: wine iexplore.exe http://www.webstandards.org/files/acid2/test.html The Gecko 1.9 branch which Firefox 3.0 is based passed this test almost two years ago, so the latest Wine Gecko could not have been from this branch. It fails badly *just like the real iexplore.exe* [Laughing] Does anyone know which Gecko version it is based on aside from "the latest"?
