OS: Windows 10 - 64bit
Copy & Paste via keyboard (Ctrl +C / Ctrl+V) don't work
Effect: Known shortcuts / workflows not supported
To reproduce:
1. In XnView select a folder in the folder tree. The folder should be a folder with few contents.
2. Press Ctrl+C
3. Select another folder in the folder tree.
4. Press Ctrl+V
Actual behaviour (bug): Nothing happens

Expected behaviour: Ctrl+C should have copied the selected folder to the clipboard and Ctrl+V should have copied the folder.
Note: "Del" key doesn't work in the folder tree either but I'm a hesitant to ask to support this dangerous shortcut.
