I'm facing a problem with the Windows version of my MD editor / browser, using links. I am using the links to navigate between pages in a folder.

On Linux, when the links are clicked, the new page simply displays in the QTextBrowser as intended. However on Windows, Notepad opens.

Here is the method I wrote to handle clicking links :

void Editor::FollowLink(const QUrl& followedFile){

    QUrl resolvedURL = GetCurrentTab()->document->baseUrl().resolved(followedFile);
    qDebug() << "The resolved URL is" << resolvedURL.toString();

    QString filePath(resolvedURL.toString());
    qDebug() << filePath;


    if(!filePath.isEmpty()) {

        QFile openedFile(filePath);

        if(!openedFile.exists()) {
            qDebug() << filePath << " does not exist.";
                return;
        }

        if (!(openedFile.open(QIODeviceBase::ReadWrite))) {
            qDebug() << "Error : File could not be opened";
            return;
        }

        GetCurrentTab()->renderDocument->setBaseUrl(resolvedURL);
        GetCurrentTab()->document->setBaseUrl(resolvedURL);
        GetCurrentTab()->editor->setPlainText(openedFile.readAll());
        GetCurrentTab()->browser->setSource(resolvedURL);
        GetCurrentTab()->RenderDocument();

        openedFile.close();
    }
    SetTabTitle(filePath);
}

My browser widget has setOpenExternalLinks(true). Moreover, Notepad is not set as the default application for Markdown, but manages to "steal" the file opening from my app ?

What could be happening here ? Thanks for your answers !
