Hi, this verify test need the user click the app: hyperlink in browser,
so it is hard to write a test in dlls/ieframe/tests.

I upload the test html file and a test exe here:
http://www.imakevideo.com/app.html
http://www.imakevideo.com/mfc_web.zip

To run the test, extract mfc_web.zip, then run the mfc_web.exe, click the Go button;
A message "BeforeNavigate2 app:xxx" will popup when click the app: hyperlink 
if the BeforeNavigate2 event was triggered as like IE in windows, or nothing.

It doesn't seem right. There is nothing special about app: protocol handling, BeforeNavigate2 should be called in this case the same way as for any other protocol. You need to find the real reason why it's not called instead of calling it in an error case. The bug is likely to be in mshtml.
