I am using WINSCP 5.11.3 (also tested 5.13) in german Windows 10(x64) and realized that my F5 key (donwload/copy) is not working.
I configured Commander Mode and every other function key like F2, F4, F6, etc. is working as intended.
But when pressing F5 nothing happens at all. When I use the context menu and choose download or using the hotkey toolbar with the mouse everything is working fine.
In every other program the F5 key is working fine.
I even checked an online Keyboard-Checker to make sure it's working fine. :D
I hope this is a known and simple problem and someone can help me because it's driving me crazy. :/
