Has anyone tried the Qt 4.2 release and VTK 5.0.2? I am running XP SP2 with the prebuilt binaries from TrollTech for Qt 4.2. I rebuilt VTK 5.0.2 against Qt 4.2, moved the plugin to the QtDesigner plugins Directory, launched QtDesigner and now the QVTKPlugin is not recognized. Any one else have this problem? Thanks Mike Jackson
