This is not enough information to find the cause of the problem, can you please provide a log.

You need to use the NVDA review cursor to read the OCR text, not the system caret. This is by design; the text isn't actually available using the caret.

That said, errors when you try to move the caret still aren't ideal. Ideally, the caret should just work as normal, though I'm not sure how to implement this.

Thanks for that, and I agree with you about the errars.

NVDA is still doing this.

  1. Open up a window wich I know has a picture in it that has text in it.

  2. Run OCR with NVDA plus R.

  3. Try and use your aro keys to read the OCRED text. NVdA gives me the following errar:

ERROR - eventHandler.executeEvent (15:26:24):

As noted in comment:2, you aren't meant to be able to read the OCRed text using the arrow keys.

These issues haven't been resolved yet. Any progress on this?
