Drops a mule (even with 2 windows) (Diablo 2)

Hello everyone, I didn’t go to d2 for a long time, but after the reset I decided to risk my time.
The essence of the problem: the second window drops, regardless of whether I'm in the same game as the main one or not. (That is, if the main one, for example, in the game Br1 and the mule in the game GoTradePoconi, then the window that hangs second in the process will drop within a minute.) I have not tried to launch more than two windows yet.
PS I know that the administration does not consider drops to be a problem in multi-windows, however, it is very annoying that you cannot get a mule to get more exp. If anyone had similar troubles and found a solution - unsubscribe, if not laziness.
