While anonymization or uploading is taking place, the user (out of impatience or uncertainty) may try to click them again, which may produce unexpected results. They should be disabled until the current processing (anonymizing or uploading) is complete. This would also provide visual cue that the program is working.
Another visual cue would be to also show a progress bar that indicates 'global' progress instead of progress bars for each individual series. It might even be a replacement for the current progress bars, as it would de-clutter the screen.
