In mIRC 6.01 (and maybe 6.0 and 6.02) whenever a connection was established with a server, but before the two commands needed to log on to a server (USER and NICK) were processed by it, the titlebar would change from "connecting to <server>" to "logging on to <server>". And since mIRC 6.03 the titlebar just stays at "connecting to <server>" before the logon process is completed, unless the nickname and alternate nickname are already in use.
I used to find "logging on to <server>" useful in detecting if a server was down or just lagged, since sometimes you can easily establish a connection with a server, but it takes some time to log on to it.
Is this a bug or just a forgotten feature?
