What's in the title.

No. Once you′ve closed them they stay closed.

Just, I remember waaaaaaay back in the day when I was playing on a... ummm... unofficial copy, that also wasn't patched, they did. Nowadays I'm playing a legit Steam GOTYE Deluxe (and I also have a Russian retail GOTYE) with all the UOP fixes and no mods, so that's why I'm asking. Good to know my efforts in closing them aren't in vain.

Well, I can′t say for unofficial, unpatched, illegal pirate-versions of the game
