It was a bug in InGuiThread.h, see commit message: "bind makes a copy of the arguments by default. This is secure if the bound object survives the existence of the arguments, but it also breaks "change by non-const reference" parameter passing, like in Alert::askForString. Here the arguments exists the whole bound function call so we could pass by reference." > I think I understand it now, though Multi threading isn't that hard ;) And have a look at bind: "you can go a long way with just boost::bind" Peter
