Yes, irritates the hell out of me too. I just can't ignore them and feel compelled to open them up and close them with 'X' every time.
If this isn't fixed in the next patch, given what a simple matter it is, I might lose my sanity
I saw an entry in one of the .cfg files stating something like "tutorial_completed=1", so the game only needs to check that value. Well, unless that line is a leftover from SH3 or 4...
On a related note, I would like the option of also being able to close my current objective(s), so that slightly ugly yellow exclamation mark isn't permanently at the top of my screen. I can always open the Captain's Log to view it/them again... I really don't need a constant reminder of my current task. It's not like it tends to change
that often.
