When adding an entry, if you drag a file anywhere outside of the chosen directory (i.e to the sidebar, or to another file explorer window), the GUI will freeze.
This was found and tested on Windows 10; I was unable to reproduce it on Linux Mint due to being unable to drag files within the window opened by NBT Database.
Steps to reproduce:
- Add an entry -> Select File
- Attempt to drag any file in the opened directory to the sidebar, above the header column (Name/Date Modified/Size, etc.), or just out of the window
- NBT Database will freeze up, and will need to be killed via Task Manager
