In my case it started when I upgraded to that version and simultaneously from 32 to 64 bits.
It mainly happens when I launch a file outside PsPad, and by outside I mean windows explorer and Jedi VCS. Most of the time is with .SQL files. It also happens when the clipboard becomes "stuck" (an application didn't close it) but that happened in previous versions -- <https://forum.pspad.com/read.php?4,76970,77502> PSPad freeware editor https://www.pspad.com
