I am trying to find a reason. Actually, I fixed much crashes reasons already. I use PSPad daily and this problem doesn't occurs for me, so it's hard to find anything.
What highlighter do you use? Can you disable highlight matching brackets in the program settings / Editor? This is the biggest suspicion what can cause it. -- <https://forum.pspad.com/read.php?4,76932,77849> PSPad freeware editor https://www.pspad.com
