Thanks for descriptions, but it might be more helpful if you can write which encodings those files are written with, and whether you use regular expressions, or escape sequences including new lines. A possible reason for the delay is that EmEditor internally works in Unicode, and it support Unicode-aware regular expressions. You can write exactly what you search for, and what the files are like, and you can email me sample files and more descriptions at tech@emurasoft.com
