RouterOS v5.8 - BUG

RB433AH, WinBox 2.2.18, RuterOS 5.8.
All time when I try change “Data Rates” in wireless interface and pusch button “Apply” winbox logout !!
Why ?
In version 3.30 and 4.17 with winbox 2.2.18 this is not happening.

i tried it and nothing happened for me.

RB433AH + 5.8.

Through what interface are you connecting? Are you using MAC or IP address in Winbox loader?
