Okay, that is very helpful to find the problem. It would be useful if you left out part of the search string to see if Emacs fails to find that or the other part. Try e. g.: C-M-% ^ *\(//\)whatever or C-M-% \(.*'n',\)foobar >>Are you sure you really >> did C-M-% and not M-% ?

Okay, that is fine, too. Greetings Malte
