Double Commander

I have got a notebook. A few network drives are mapped. When I move to next location (disconnect from network and reconnect on next location), then sometimes error message is shown.
Network drive has bad ikon (as disconnected), but I am able to open it and work with this drive without any issue. Problem is only with showing error message, no others problem has been detected.
