accessibility problem on Windows

["Eric S. Johansson" <esj harvee org>]

I use and am dependent on speech recognition (NaturallySpeaking) to do 
most operations with computers.  With NaturallySpeaking version 6, the 
basic "correct last utterance" system worked within gtk+.  On 
NaturallySpeaking 7, it doesn't.  when I complained to NaturallySpeaking 
technical support, they said it was because the application for using 
"nonstandard Windows".  Therefore, I am trying to collect information 
about what kind of Windows interfaces gtk+ uses so I can push back on 
scansoft.  Unfortunately, I know squat about Windows APIs and so I'm 
asking for some expert guidance.

Assuming there are only a couple of interfaces that create text based 
Windows such as those used in the gaim text entry box, what APIs are 
used in Windows to create those effects?  I've been told they are also 
called edit controls?

in any case, any information would be most welcome.
