Using AS since years. Best investment ever

But now I've got a problem.
Environment:
Windows 10 x64
Salamander 3.08 x64
When I map drives using a batch file with "net use ..." commands, Windows Explorer shows the mapped drives. But Salamander seems to now nothing about the drives. Even when I map them using Salamander menu, they are gone after restart, even if I enabled them to be persistent.
You can see in attachment.
I tried to close Salamander and reopen. No success.
I tried starting batch file with Salamander closed or opened. No success.
This is very annoying. Never had these problems on Win7 or before with Salamander.
Thanks for help
