Comment 1 for bug 392343

I'm putting in another bug about a UI issue...but in the Drizzle project, we have come across this issue as well. Basically, here is what you need to do to get a new merge diff:

1) Click the little yellow edit icon next to the *status* of your original Merge proposal.
2) Select "Resubmit" from the dropdown list
3) Click "Change status"
4) Page will reload showing additional commits which will now be used in generating a new diff. Click "resubmit" button after reviewing these commit messages
5) Page will reload, *but will not have the new diff until you hit F5 or click the reload button on your browser*

Hope this helps!
