Before NVDA I used Blindows as my prefered screenreader. Blindows needs a tool like Webbie to accessing Internet Explorer, and it is called Webformator. It is available for free:
http://www.webformator.de/englisch/index.php
When I start the Internet Explorer, Webformator is started as an IE helper and NVDA begins to read the complete Webformator screen. Unfortunately NVDA stop reading when I navigate by cursor or tab key.
If it is no matter to solve this problem I ask you to build in the access for Webformator.

I have found out webformator window reacts to edit control like messages. If I am trying it with the patch I've attached I can use arrow keys to navigate webformator window. However line breaks are wrong and I am unable to find where it fails.
I will perhaps look more into it later.
Has anyone an idea?

Okay, I have found webformator window gives incorrect line offsets.
It does not handle empty lines properly.
For example:
The first line has text
"first" indexed from 0 through 4. Then there is a new line character indexed 5. Then there is another new line character indexed 6. And finally there is a text "third" indexed 7 through 11. Now let's send a EM_LINEFROMCHAR message into this control. While giving offsets 0 through 5 it's all fine, control gives back number 0. When offset equals to 6 is given it returns 1 - stil it's fine. When offsets 7 through 11 are given to the EM_LINEFROMCHAR message it returns back 1. And this is wrong unfortunatelly these characters represent third line. While indexing starting at 0 it should be 2.
Is anyone here up for the task to workaround this?

I've found webformator window also responds to RichEdit like window messages and that's working correctly. Is there something else missing to make webformator useable with NVDA? The patch is updated accordingly.

This should not block the next release, but we'll certainly take the fix if it is confirmed to work.
