I'm using WinXP SP2.

When I upgrade 6.2 to 6.21 and connect, the new log is in "mirc folder\" but not the original folder, "mirc folder\logs\".
And the filename in "mirc folder\" is #channel.1.log
If I disconnect, the session will be as follows:

Session Close: Fri Nov 24 14:32:18 2006

Session Start: Fri Nov 24 14:32:18 2006
Session Ident: #channel
[14:32] * Disconnected

When I close mIRC, the session will close again:
Session Close: Fri Nov 24 14:32:42 2006

and rename/add to #channel.log

The "View logs", of course, can't view the log after upgraded.
I do not automatically log all channels but one by one.
