If I delete a file, the cursor goes up, instead of down. If there is 3 files named A, B, C. Delete file B and the cursor (the next selected file after deletion) is going on A file, instead of selecting C file. So if you delete withcout checking the name, you are going from Z to A names. The files are ardered from A to Z on name.
Selection handling changed in 1.6. After a delete no file will be selected.
