Panthera, - Yes, as far as I know, the wide screen version is still available!
I'm sure Morgan will give you a link.
To change the size (vertically) whilst the wide version SSA is on, is just a matter of adjusting your monitor settings, (if required!), to the correct proportions. - Once set, your monitor will remember them and always show the wide version correctly, - it will NOT affect the rest of your applications ........ trust me!
(Unless you have an old monitor!)
Edit! - I've just seen your above post ...... When you say "greyed out" where are you looking?
