Let me explain a bit more what happens here.

(I've tried to also run rebaseall, but with no different result.)

BRLTTY starts with a recent cygwin1.dll,, and the initial startup
message is displayed on my braille display. Normally, it should be
possible to press a scrolling key to make the message disappear, but
nothing happens. If I, however, press the BRLTTY paste keys, the
display is updated with the text at the current screen line. If the
current line is a terminal prompt, and I type some text, the display
isn't updated until I again press the BRLTTY paste. If I press the
scroll up key for instance four times, and then press the paste keys, I
can read the content of that line.

I'm using a Handy Tech Modular Evolution braille display, and so the ht
driver in BRLTTY are used. The problem may be related to the braille
driver in BRLTTY, I don't know.

Hope this helps.

Lars
