Hello,

The channel window does not scroll forward when new messages arrive, if the channel menu is open with a nick selected.

Repro steps:
1) Join a test channel with two nicks.
2) With one nick, send a message, ten repetitions every five seconds: /timer 10 5 msg #[the channel] testing
3) With the second nick, right click on the first nick when it appears, leaving the menu open. The window does not advance the next time the first nick sends the message. The scroll bar shows the message arrived, but the window is frozen.

Particularly with script commands, new messages should be visible while you're looking through the channel menu. Users that need to see the original nick and line when it might scroll off the screen, can create a disabled menu item which shows that information.
