Don't Go-Amigo!!
From the description, it sounds more like Go-Amigo's caught in the middle
more than anything else. I don't know any distributors who like to handle
update stuff.
I'm not sure that Manx has an 'official' policy regarding buying an 'old'
version right before or after a new release comes out. I can say though
that I've seen lots of individual cases where we've given the update at no
cost when the time period was reasonably close.
