Steps to reproduce:

Open a text editor, I tried notepad, thunderbird new message and this edit field on Google Chrome.
Press a cursor routing.
The cursor will be positioned a charachter after your desired position.
For example if you have the word NVDA, and you want the cursor to the D charachter, after pressing cursor routing you will be positioned on the A charachter.
This behaviour is present also if you select braille tether review cursor, instead of focus.

Expected behavior:

Cursor should go to the proper charachter.

Actual behavior:

Cursor's position is one charachter after you expect.

System configuration:

NVDA version: next-14283,1e5c5581 (August 2, 2017).

NVDA Installed or portable: portable.

Other information:
running windows7 64bit with a Lilli display braille.

Name and version of other software in use when reproducing the issue:

Other questions:

Does the issue still occur after restarting your PC? Yes.

Have you tried any other versions of NVDA? YES, 2017.2 is broken too.
