Serious but simple issue with "Move To..."

[m.Th.]

In short: When the user moves one folder on another disk the files are moved ok but the folder isn't deleted from the source dir.

How to reproduce:

1. Have a directory structure similar to

C:\foo
C:\foo\dir1
C:\foo\dir2
...
...And in each subfolder several images.

2. Go with XnViewMP in c:\foo\dir2 and leave it to catalog them.

3. Go up in C:\foo and select the 'dir2' folder, right click and chose 'Move To...'

4. Select 'D:\dest\' as destination, press Move and wait to finish

Expected: All the files are transfered to "D:\dest\dir2" and 'dir2' is deleted from 'c:\foo'

Actual: All the files are transfered to D:\dest\dir2 but 'dir2' remains as an empty and locked dir in 'c:\foo'

When I say that it is locked it means that the user must close XnViewMP in order to delete or access it from other programs (I have a sync program which says 'access denied' on such folders).

Can someone reproduce it? Pierre can you fix it?
