When either the treebar or switchbar is enabled, mIRC stalls for a second or so when connecting and joining. This didn't happen on previous versions, so I assume it can be fixed.
Depending on connection speed and/or pc specs it might take different amounts of servers to connect to and channels to join, but for me I join 3 networks, 4 channels one the first network, 3 on the second and 1 on the third.
I have a /servers alias which connects me to multiple networks, joins channels, identifies to nicks, ops me using various bots, etc, so it triggers a whole chain of events. If you can't reproduce the problem I can give you the code I have in a pm/email. I'd rather not post it publicly.
