You don't give any idnication of how old that snapshot is. Som eof the emacs-snapshot packages I've seen are very old - in fact, I saw a ubuntu one today that had a date in 2007!!! At various times, I've seen similar things to what you appear to be describing. In my case, it has been fixed with re-fontifying the buffer using M-x font-lock-fontify-buffer What you are observing are probably intermidiate bugs in the code. Remember, emacs-snapshot is a snapshot of the CVS development tree and you can expect to encounter things like this. Use M-x emacs-version and find out when the package you are using was created. If its older than a few weeks, find a newer version or build from sources. Its likely the problem has been fixed in later versions (though its just as likely it could come back - thats the downside of using development code). Tim -- tcross (at) rapttech dot com dot au
