I've been using ccase.el with 21.2.34 without any real problems for a couple of weeks. (Very nice!) However, it doesn't work so well with 21.2.35 now. The major problem thus far is that file name completion doesn't work very well at all. With 21.2.34 I could do filename completion with view tags just fine. Now 21.2.35 does weird things. C-x C-f /view/<viewtag>/ <TAB> is ok (where <viewtag> is some view tag). If I continue with /view/<viewtag>/v and press TAB, I get a beep and the cursor moves back to just after /view. In 21.2.34, this would complete correctly to /view/<viewtag>/vobs. Since the only difference is that I've upgraded to 21.2.35, I assume the problem is due to some change in filename completion in 21.2.35? Ray
