Particularly since it's buggy, could the activity flashing be disabled at the user's choice? I'm running Win2k, and know there are issues with that that are OS-based: autohide taskbars reveal themselves when flashing starts, which is really annoying.
Though it *could* be that mc isn't the cause, and that it's actually the OS triggering the flashes.
