There are 2 ways to reproduce this:
Method 1
- Load multiple files into Mp3tag.
- Select 1 and only 1 file: observe the selected file count is 1 on the status bar.
- Unselect all files either by Ctrl + U or via the Edit menu: observe that the selected file count remains 1 even though no files are highlighted. Also, the Save button is greyed out.
Unselecting works properly if multiple files have been selected.
Method 2
- Load multiple files into Mp3tag.
- Select 1 or more files.
- Open the filter view (F3 or via the View menu) and apply a filter that returns zero matches (for example: %_filename% IS "").
- Close the filter view: observe that no files are highlighted and the Save button is greyed out, but the number selected remains as when first selected.
