@Nikita-Sourine Exactly what one would expect if an external entity is “continuously” updating the file. In fact, the same thing should happen if you also click “Yes”! Once you have the service stopped, try looking into Settings->Preferences->Misc. If you uncheck Enable in the File Status Auto-Detection box, that might fix your issue (not entirely sure, plus I use an older program version and your UI may not match mine).

@Vince-kuzanagi I tried it on similar data with 2000 lines with no problem. Can you post your complete BEFORE and AFTER text (maybe on textuploader.com) that this problem happens with? [Make sure the problem happens with the XXX’s rather than just the real phone numbers…I’m sure you don’t want to post the real phone numbers…] Also try to describe exactly what you do: where is your caret before you start?, etc. Sometimes there is more to what you are doing than you say, and that can be the thing(s) that reveal a bug… Also, what version of Notepad++, including whether or not it is a 32 or 64 bit version.
