Replace all double quotes freezes over a certain number of lines
- 
 Using 7.9.1 64-bit, I have a list of usernames, one per line, surrounded by double quotes. I am trying to use Replace All in Normal mode to replace double quote with empty string, in the whole document. If I have 250 lines, it works as expected, but with 500 lines or more, I get a progress spinner that remains for an inordinate time (MS Notepad replaces in 2700 lines nearly instantly). I don’t know if it would ever finish; I haven’t wanted to wait for it. Anyone seen this? 
- 
 500 lines is tiny, and shouldn’t have a problem. Could you give a screenshot of your Replace dialog? 
- 
 Further:  
 =>
  lasted less than a second from hitting Replace All. Please also give your ? menu’s Debug Info (copy/paste from that window to here)

 “aaaron”
 “aaden”
 “aagarwal”
 etc.I’ll hold off trying a reinstall to see if you want to try anything else.

 I would give it a try without having 3rd party plugins installed. 
 Temporarily rename plugins directory from %APPDATA%\notepad++
 Start npp and redo the test.

 @Ekopalypse Thanks. I removed and reinstalled XML Tools and that fixed it.
