This problem didn't happen before.
This problem happen only on thumbnail view, don't happen on detail view and icon view.

Problem:
When the folder is updated, multiple file selection will be canceled.

How to reproduce:
1. Open a folder containing multiple image files.
2. Change the folder view to thumbnail view.
3. Select multiple files.
4. Open this folder with File Explorer, and add a new file.
5. Activate FreeCommander.

Result:
When this foler view was updated, multiple files selected was canceled.

Not fully confirmed.
The selection is still there, just a little bit dimmed.
If I make a copy or something else with them, it works as desired.

I can confirm it with default settings only, in this case, after copying any file to that folder in File Explorer, selection of multiple files is removed immediately, even before activating FC window.

With my custom settings, using NC-mode, I can't confirm it at all, selection is always preserved.

OK, so the workaround is to use NC-mode, even with default settings + NC-Mode, selection is always preserved.

Thank you for testing.
I found an another problem related this problem.

Problem:
"Restore/Load selection" feather doesn't work on Thumbnail view (Not NCmode).

How to reproduce:
1. Disable NCmode.
2. Change to Thumbnail view.
3. Select multiple files.
4. Use "Edit->Save Selection" or "Edit/Save Selection to file".
5. Use "Edit->Unselect All".
6. Use "Edit->Restore Selection" or "Edit->Load Selection from file".

Result:
Only 1 file is selected.
This also doesn't happen on NCmode.
