    # localRoot is is an empty topmost root window that is hidden by withdrawing it
    # but localRoot needs to be centred, and lifted and focus_force used
    # so that its child dialog will inherit focus upon launch
    localRoot.overrideredirect(True)
    # center on screen but make size 0 to hide the empty localRoot
    w = localRoot.winfo_screenwidth()
    h = localRoot.winfo_screenheight()
    x = int(w/2)
    y = int(h/2)
    localRoot.geometry('%dx%d+%d+%d' % (0, 0, x, y))
    localRoot.deiconify()
    localRoot.lift()
    localRoot.focus_force()

    fpath = tkinter_filedialog.asksaveasfilename(
        parent=localRoot,
        title="Save ePub3 as ...",
        initialfile=fname,
        initialdir=_USER_HOME,
        defaultextension=".epub"
        )
    # localRoot.destroy()                                                                                                       
    localRoot.quit()

If this added code will not hurt anything on Windows or Linux I can add it to the plugin to prevent this type of issue from happening to others.

Sorry I'm late to this, but the new code doesn't work for me on Linux (Sigil HEAD/Python 3.6). The file dialog launches behind Sigil's window, and nothing new opens on the taskbar to even indicate anything was launched. Until I happened to minimize Sigil, I thought the plugin was hung up.

The problem on Linux seems to be the line:

localRoot.overrideredirect(True)

When I comment that out, the file dialog pops in front of Sigil and a new item appears on the taskbar.

If that line is absolutely needed on Macs, you may want to limit using it on that platform with an "if sys.platform.startswith('darwin')"

EDIT: indeed, changing the code to the following makes everything work "normally" on Linux/Windows for me. I assume it would fix the Mac issue as well.

    localRoot = tkinter.Tk()
    localRoot.withdraw()

    if sys.platform.startswith('darwin'):
        # localRoot is is an empty topmost root window that is hidden by withdrawing it
        # but localRoot needs to be centred, and lifted and focus_force used
        # so that its child dialog will inherit focus upon launch
        localRoot.overrideredirect(True)
        # center on screen but make size 0 to hide the empty localRoot
        w = localRoot.winfo_screenwidth()
        h = localRoot.winfo_screenheight()
        x = int(w/2)
        y = int(h/2)
        localRoot.geometry('%dx%d+%d+%d' % (0, 0, x, y))
        localRoot.deiconify()
        localRoot.lift()
        localRoot.focus_force()

    fpath = tkinter_filedialog.asksaveasfilename(
        parent=localRoot,
        title="Save ePub3 as ...",
        initialfile=fname,
        initialdir=_USER_HOME,
        defaultextension=".epub"
        )
    # localRoot.destroy()
    localRoot.quit()
