@PeterJones
Thank you for your heads up!
The bug (not an easy one) has been fixed:
https://github.com/notepad-plus-plus/notepad-plus-plus/commit/bc2e6891858cb646ce9fa54b7be206675325ed97
It’s 4:30 AM here so I’ll do RC2 rather tomorrow. In the meanwhile please try the Appveyor’s build, and let me know if some side effects that I missed. Thank you!
