title: Are there fundamental differences between TextBoxes in Windows 7 and Windows XP
body: <p>I've written a windows forms app in .Net 4.0 that utilizes a text box for user input. The intent of the program is to accept input from a stenography machine; through which a transcriber would be actively captioning live video.</p>
  
  <p>The problem I am experiencing is that in Windows XP environments, the text box is performing as expected, accepting QWERTY keyboard input, as well as input from the stenography machine. It's my understanding that the machine integrates as the equivalent of another keyboard, but for some reason in Windows 7, the text box is accepting input from the QWERTY board, but not from the Stenography machine. </p>
  
  <p>This brings me to the question at hand - are there any fundamental differences between a text box in Windows 7 and Windows XP, and amongst those are there any that could affect the manner in which it handles text from the OS?</p>
  
  <p>Thanks much, I hope I've been explicit enough.</p>
