Is this accepted practise?

I don't think it is much of a problem, but I see no reason to open a scn beforehand other than finding out whether a scn will be worth playing or whether I can see right away the it is another crap scn.

Then again, it is only one moment in time and after the first moves everything is different. Every scn you play more than once would have the same issue. Still people play some scenarios over and over again.
Playing blind is nice, but sometimes it becomes painfully apparent that the player has less info on the battlefield layout and has less clue what he is supposed to do than the historical commanders did.
