Great Tool! Highlighting works again with 22.214.171.124. Thanks for the update! It is handy to see the exact part of the line that changed. Keep up the good work.
As noted from wikipedia, notepadd++ all versions even the latest ones are highly unstable. Donot use it, or you'll lose the codes while writing.
Notepad++ hangs when i have opened a few relatively large xml files and start switching between tabs. Especailly, if i switch from a non-xml tab to that an xml containing tab with collapsed nodes. Having removed the plug-in - the issue is gone.
