Something else is going on here. I reverted to Reverted to version 5.0.2.351 (12/23/2019) and I am still having the same crashes after drag-and-drop. I definitely was not having this problem in early 2020, so something else has changed.
Also, PSPad (all versions) sometimes adds a line of about 6 gibberish characters in column 0 of what seems to be a new line. This shows up mostly (entirely?) on XML files I am editing and the XML parser immediately spots the problem. It does not look like the data is getting corrupted. It seems to cleanly add a new line of 6 gibberish characters which I can just as cleanly delete. I am having some level of problem on two different machines with rather different configurations and tool sets. For example, the one that is displaying the problem less often is tightly tied into Microsoft and replicating 10s of gigabytes of data to OneDrive. However, on that machine I am using PSPad less intensively. On the machine which is showing the problem more often, I am not using OneDrive at all, but working intensively in DropBox. The drag-and-drop operations that cause crashes are all coming from DropBox folders. At any rate, I will look at the latest 5.0.7 build and keep trying to isolate.
