#317 selecting multiple files always misses the last file

[Rick Ekle]

1. Open an archive with 7Zip in Windows
2. in the file list, click on the first file to select.
3. Hold down shift and click the last file to select.
4. 7zip will select all the files between the first
file and the last file, including the first and last file.
5. the selection cursor is now on the last file.
6. Hit the Extract button to extract all the files
selected.
7. 7Zip will extract all the files EXCEPT the file that
currently has the cursor over it. It ALWAYS misses
this selected file. This means that you have to go
back and choose that file again and extract it separately.
