I noticed Ben was having issues with it seeming to not find all cases.
What seems to be happening is, it finds some cases over and over and over again before it gives the popup that says “no more”. In other words, for some reason, it’s an out-of-order search. If you skip replacing some cases, it revisits them multiple times between finding new occurrences. Annoying, and I bet (but I don’t bet very much) it’s part of some code intended to do “recursive replacements”, like if you replace GNU with GNU’s Not Unix, it would revisit “GNU’s” to see if you want to replace that as well.
So, you have to keep hammering at the keys/clicking the icons till you get the popup to be sure you looked at every case.
