When a file upload is in progress, the dataReceived, changed, and fileToLarge signals are emitted as expected. In internet explorer 7, chrome, and firefor also the uploaded signal is emitted. But when loading the same page in mshta.exe (basically a wrapper around IE engine) the uploaded signal is not received...

Anyone any idea what prevents the signal from being sent?

This is the code that creates the widget:

    std::string s_template = "<div class=\"form\">"
                             "<p>"
                             "<label>Select the file to upload: </label></p><br />"
                             "<p>${upload_widget} ${upload-button}</p><br />"
                             "<p>${pbar}</p>"
                             "</div>";

    template_ = new WTemplate(s_template, center_);

    fu_ = new WFileUpload();
    fu_->setFileTextSize(40);

    progress_bar_ = new WProgressBar();

    template_->bindWidget("pbar", progress_bar_);

    fu_->setProgressBar(progress_bar_);

    fu_->changed().connect(this, &HelloApplication::FuChanged);

    fu_->changed().connect(boost::bind(&HelloApplication::FuStatus, this, "File upload changed"));
    fu_->uploaded().connect(boost::bind(&HelloApplication::FuUploaded, this, "File upload finished"));
    fu_->dataReceived().connect(boost::bind(&HelloApplication::FuStatus, this, "Data received"));
    fu_->fileTooLarge().connect(boost::bind(&HelloApplication::FuStatus, this, "File too large"));

    template_->bindWidget("upload_widget", fu_);

    button_upload = new WPushButton("Upload");
    button_upload->setDisabled(true);
    button_upload->clicked().connect(this, &HelloApplication::FuUpload);

    template_->bindWidget("upload-button", button_upload);
