 I just ran the 32 bit test bundle. When I load pages now, NVDA doesn't
 seem to treat them as a web page, though it is able to tab around to
 links, form controls and such. I am, however, unable to switch to browse
 mode to interact with the document like a webpage (I tried pressing
 NVDA+space, nothing happened). To see what NVDA should be doing, try going
 into Firefox or Chrome, and navigate by element, such as to next heading
 (press h) or read the webpage with arrow keys. I suspect that the fix is
 simple, as NVDA definitely sees the rendered content, it just doesn't seem
 to treat it as a web document.
 Hopefully I make sense - I'm not very well-versed in terminology.
