NotePad++ crashes using compare plus immediately after clicking compare
-
Hello, Just needing some help to see if anyone may know how I can solve this issue. I have used Notepad++ with the ComparePlus plugin for a couple years now but for some reason today when I try to compare 2 xml files everytime I click compare it crashes and closes. No error just closes. I tried removing all other plugins and also made sure both the plugin and notepad++ are up to date and the issue persists. Any help would be greatly appreciated.

I had been hoping the plugin’s author, @pnedev, would have responded by now. I might suggest trying without the XMLTools plugin, to see if it’s a strange plugin interaction. Or if you could give some clues as to whether there’s something unique about these XML: are they very similar files, with only a few lines different? Or are they highly different, with only a few lines of similarities? Big files, or small? Which ComparePlus options are enabled (do a screenshot showinng the entire ComparePlus sub-menu, so we can see all the checkmarks).
(ComparePlus has never crashed on me, so I’m just giving some generic debugging suggestions. If anyone else has ideas, feel free to chime in.)
