No...
/close -m closes ALL query windows.
I hate it when people don't listen to what you tell them.
The command to close A SINGLE query window, is /closemsg <nickname>.
/close -m closes ALL query windows
/close -m <nick> closes the query to the specified nick
110.Added /close -icfgms [nick1] [nickN] which closes windows of
the specified type and nicknames. If no nicknames are given,
all windows of the specified type are closed.
i = only close inactive windows (doesnt apply to message windows)
c = chat
f = fserve
g = gets
m = message windows
s = sends
111.Removed /closechats, /closefserves, /closedccs commands. These
are replaced by the /close command.
/closemsg was not removed, but is no longer mentioned in the help file. (It is still used in the default popups.ini though
)
