hexaae: Was this a GOG version only bug or also in the original CD ROM version?
EDIT: just tested on a CD ROM original version and the answer is YES, was a bug of the original game :(
I'm also affected by that bug. It would be helpful if we could know where in the savegame the value for the option 'text display' is stored. Knowing that, we could at least modify it's value with a hex editor!
Maybe someone can post three savegames, each loaded from a master save, one for each value of 'text display'? We should be able to see where the option is stored and change it by hand once.
Or could someone post savegame from game start where simply the text option is set to 'show until enter key pressed'?
EDIT: I figured out that those settings are not stored in the savegame, so it won't help. If we find a hotkey for changing text mode, then we could use that. Otherwise as workaround: hit CTRL-S (or use game options) to disable sound, that way you can at least read the text because without sound, the text boxes won't disappear on their own.
