Bad cursor position in the cygwin's mintty terminal

[jupiterfr]

When I use the cyngwin's mintty utility my braille refresh fine, i.e. when I modify the line, all characters appear synchronously.
The only big problem is that the cursor position is one character after the correct position.
I would like to use this utility because all other ssh terminal such as teraterm has problem refreshing my braille display sometimes, and braille loose focus.
this problem has been constated in nvda ver 2011.2 and nvda 2011.3beta1.

Any reason you aren't just using the Windows Command console (in which you can also run Cygwin apps)?

My interrest using cygwin's mintty is for emacs for example.
Cygwin's mintty allows you to use any keyboard key as alt-f4
shift-arrows etc as in normal windows app. If I use a linux system
through the cygwin's mintty, I can select text for example with
shift-arrow as I do in windows.
Another good feature, is that cygwin's mintty automatically set cursor position when pressing left mouse button, i.e, if braille is used, I use the routing cursor key.
It is not a blocking bug but I think that this terminal is very
accessible except for the one character after problem.
