I'm sorry, but we cannot fix that. What happens is that the connection is created in a background thread and this thread is simply killed when the user cancels the connection request before the usual timeout kicks in. However, this seems to leave a lock in place or similar, so every following attempt, even from a new thread, blocks.

The work around is to wait for the timeout to kick in (you can set a very low value for that if you frequently have non-working connections) and then try again with another connection/host. This would then work as usual. Another option is to just cancel the connection dialog entirely, which closes MA, and try again.
