(sigh) As mentioned, the video=640x400 appears to have caused my initial problem, and changing it to video=640x480 took care of that - but it's left me squinting at my console screens because of the smaller font, and I'd love to find the way to restore the slightly larger font. However, I surrender, glad to have fixed the main initial problem. :)
