Seconded. I've missed so many hails I can't remember. For some reason I only notice them after I SCed out of range.
Also, after a CMDR hails you, you should be able to respond even after you get out of range (while in the same system). When I get hailed in SC I usually lose the contact before I get a chance to bring up the comms panel and respond.
Yep! I agree with this. I've missed loads of messages because I've been concentrating on other things.
