W7x64, HxD 2.2.1.0
- Open three files, size does not matter.
- Calculate MD5 for one file -> At the bottom of the screen the checksum will be displayed along with a combobox to choose the other files.
- Click on the combobox and the file list appears.
- Use your keyboard(!) to move up/down to the next file.
=> Stream read error (the checksum will be correc though).
Switching via mouse works fine.
